With this simple tutorial I will show you how to use the Robot Class in Java to control your computers mouse.

We can change the position of the cursor, left and right click, move the mouse wheel and click the mouse wheel.

For these examples you will need to make sure you import the java.awt.Robot &java.awt.event.InputEvent classes.

java code 1:

Move the mouse cursor position on screen:

import java.awt.Robot;
 
public class MouseClass {
 
 public static void main(String[] args) throws Exception {
 
            Robot robot = new Robot();
 
            // SET THE MOUSE X Y POSITION
            robot.mouseMove(300, 550);
 
 }
}


java code 2:




Click the left mouse button:



import java.awt.Robot;
import java.awt.event.InputEvent;
 
public class MouseClass {
 
 public static void main(String[] args) throws Exception {
 
            Robot robot = new Robot();
 
            // LEFT CLICK
            robot.mousePress(InputEvent.BUTTON1_MASK);
            robot.mouseRelease(InputEvent.BUTTON1_MASK);
 
 }
}
java code 3:
Click the right mouse button:


import java.awt.Robot;
import java.awt.event.InputEvent;
 
public class MouseClass {
 
 public static void main(String[] args) throws Exception {
 
            Robot robot = new Robot();
 
            // RIGHT CLICK
            robot.mousePress(InputEvent.BUTTON3_MASK);
            robot.mouseRelease(InputEvent.BUTTON3_MASK);
 
 }
}
java code 4:
Click & scroll the mouse wheel:

import java.awt.Robot;
import java.awt.event.InputEvent;
 
public class MouseClass {
 
 public static void main(String[] args) throws Exception {
 
            Robot robot = new Robot();
 
            // MIDDLE WHEEL CLICK
            robot.mousePress(InputEvent.BUTTON3_DOWN_MASK);
            robot.mouseRelease(InputEvent.BUTTON3_DOWN_MASK);
 
            // SCROLL THE MOUSE WHEEL
            robot.mouseWheel(-100);
 
 }
}

Poverty Around The World........................!!!!!!!!

Third World countries are often described as “developing” while the First World, industrialized nations are often “developed”. What does it mean to describe a nation as “developing”? A lack of material wealth does not necessarily mean that one is deprived. A strong economy in a developed nation doesn’t mean much when a significant percentage (even a majority) of the population is struggling to survive.
Successful development can imply many things, such as (though not limited to):

An improvement in living standards and access to all basic needs such that a person has enough food, water, shelter, clothing, health, education, etc;
A stable political, social and economic environment, with associated political, social and economic freedoms, such as (though not limited to) equitable ownership of land and property;
The ability to make free and informed choices that are not coerced;
Be able to participate in a democratic environment with the ability to have a say in one’s own future;
To have the full potential for what the United Nations calls Human Development:

Human development is about much more than the rise or fall of national incomes. It is about creating an environment in which people can develop their full potential and lead productive, creative lives in accord with their needs and interests. People are the real wealth of nations. Development is thus about expanding the choices people have to lead lives that they value. And it is thus about much more than economic growth, which is only a means—if a very important one—of enlarging people’s choices.

— What is Human Development?, Human Development Reports, United Nations Development Program

At household, community, societal, national and international levels, various aspects of the above need to be provided, as well as commitment to various democratic institutions that do not become corrupted by special interests and agendas.
Yet, for a variety of reasons, these “full rights” are not available in many segments of various societies from the richest to the poorest. When political agendas deprive these possibilities in some nations, how can a nation develop? Is this progress?
Politics have led to dire conditions in many poorer nations. In many cases, international political interests have led to a diversion of available resources from domestic needs to western markets. (See the structural adjustmentsection to find out more about this.) This has resulted in a lack of basic access to food, water, health, education and other important social services. This is a major obstacle to equitable development.

java program for Bouncing Ball GAME

java program for Bouncing Ball GAME
This program does a simple animation. Animation is done by creating a timer which calls an ActionListener at fixed intervals (eg, every 35 milliseconds). The listener tells the ball to move it's coordinates a little, then it repaints the panel. repaint() indirectly calls ourpaintComponent() method, which then draws the ball with the updated coordinates.

JAVA PROGRAMS 8

Write a Java program that:

i) Implements stack ADT.

PROGRAM:

import java.util.*;

public class StackADT

{

int a[];

int top;

public StackADT(int n)

{

a = new int[n];

top = -1;

}

public void push(int item)

{

if(isFull())

{

System.out.println("Stack is full");

return;

}

a[++top] = item;

System.out.println("Item Pushed");

}

public int pop()

{

if(isEmpty())

{

System.out.println("Stack is empty");

return 0;

}

return a[top--];

}

public int topElement()

{

if(isEmpty()) return 0;

else return a[top];

}

public boolean isEmpty()

{

return (top <= -1);

}

public boolean isFull()

{

return (top >= a.length-1);

}

public int count()

{

return top+1;

}

public void display()

{

System.out.print("Items In Stack Are: ");

for(int i=0;i<=top;i++)

System.out.print(" "+a[i]);

}

public static void main(String args[])

{

int x,n,ch=0;

Scanner sc=new Scanner(System.in);

System.out.println("Enter Stack Size:");

n=sc.nextInt();

StackADT st=new StackADT(n);

System.out.println("\t-----LIST OF OPERATIONS------");

System.out.println("\t\t[1].Push");

System.out.println("\t\t[2].Pop");

System.out.println("\t\t[3].Top Element");

System.out.println("\t\t[4].Count");

System.out.println("\t\t[5].Empty");

System.out.println("\t\t[6].Full");

System.out.println("\t\t[7].Display");

System.out.println("\t\t[0].EXIT");

{

System.out.print("\nEnter Choice Of Operation:");

ch=sc.nextInt();

switch(ch)

{

case 1: System.out.print("Enter Element: ");

x=sc.nextInt();

st.push(x);

break;

case 2: x=st.pop();

if(x!=0) System.out.println("Item Poped: "+x);

break;

case 3: x=st.topElement();

if(x!=0) System.out.println("Top Item: "+x);

else System.out.println("Stack Is Empty");

break;

case 4: System.out.println("Number Of Items In Stack: "+st.count());

break;

case 5: if(st.isEmpty()) System.out.println("Stack Is Empty");

JAVA PROGRAMS 7

a) Write a Java program for sorting a given list of names in ascending order.

Program:

import java.io.*;

class Ascend

{

public static void main(String args[]) throws IOException

{

int n,i,j;

String temp;

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.print("\nEnter Number Of Names:");

n=Integer.parseInt(br.readLine());

String s[]=new String[n];

System.out.println("Enter "+n+" Names:");

for(i=0;i<n;i++)

s[i]=br.readLine();

for(i=0;i<n;i++)

{

for(j=0;j<n;j++)

{

if((s[j].compareTo(s[i]))>0)

{

temp=s[i];

s[i]=s[j];

s[j]=temp;

}

System.out.println("\nAscending Order Of Names:");

for(i=0;i<n;i++)

System.out.println(s[i]);

}

Output:

Enter Number Of Names:2

Enter 2 Names:

vineela

aswini

Ascending Order Of Names:

aswini

vineela

JAVA PROG 6

Week-3:

a) Write a Java program that checks whether a given string is a palindrome or not.

Program:

import java.io.*;

class Palindrome

{

public static void main(String args[]) throws IOException

{

int i,j;

boolean flag=true;

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.print("\nEnter String:");

String s=br.readLine();

j=s.length()-1;

for(i=0;i<=j;i++)

{

if(s.charAt(i)!=s.charAt(j--))

flag=false;

}

if(flag==false) System.out.println("\n"+s+" Is Not Palindrome");

else System.out.println("\n"+s+" Is Palindrome");

}

Output:

Enter String: malayalam

malayalam Is Palindrome

JAVA PROGRAMS 5

a) Write a Java Program that reads a line of integers, and then displays each integer, and the sum of all the integers (Use StringTokenizer class of java.util)

Program:

import java.io.*;

import java.util.*;

class SumOfInt

{

public static void main(String args[]) throws IOException

{

int sum=0;

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.print("\nEnter String Of Integers:");

String s=br.readLine();

StringTokenizer st=new StringTokenizer(s,",");

while(st.hasMoreTokens())

{

int i=Integer.parseInt(st.nextToken());

sum=sum+i;

System.out.println(i);

}

System.out.println("\nSum Of Integers Is: "+sum);

}

Output:

Enter String Of Integers:12,5,3,1,2

Sum Of Integers Is: 23
