Write a java program to display all the vowels from a given string.

import java.io.*;

class Vowel {

   public static void main(String args[]) {

    String str = new String("HI WElcome!");

    for(int i=0; i<str.length(); i++) {

      if(str.charAt(i) == 'a'|| str.charAt(i) == 'e'||

          str.charAt(i) == 'i' || str.charAt(i) == 'o' ||

          str.charAt(i) == 'u'||str.charAt(i) == 'A'|| str.charAt(i) == 'E'||

          str.charAt(i) == 'I' || str.charAt(i) == 'O' ||

          str.charAt(i) == 'U')

        System.out.println("Given string contains " +

     str.charAt(i)+" at the index " + i);

    }

  }

}

Design a screen in Java to handle the Mouse Events such as MOUSE_MOVED and MOUSE_CLICK and display the position of the Mouse_Click in a TextField.

import java.awt.*;

import java.awt.event.*;

class Slip4 extends Frame

{

TextField statusBar;

Slip4()

{

addMouseListener(new MouseAdapter()

{

public void mouseClicked(MouseEvent e)

{

statusBar.setText("Clicked at (" +e.getX() + "," + e.getY() + ")");

repaint();

}

public void mouseEntered(MouseEvent e)

{

statusBar.setText("Entered at (" + e.getX() + "," +e.getY() + ")");

repaint();

}

});

addWindowListener(new WindowAdapter()

{

public void windowClosing(WindowEvent e)

{

System.exit(0);

}

});

setLayout(new FlowLayout());

setSize(275,300);

setTitle("Mouse Click Position");

statusBar = new TextField(20);

add(statusBar);

setVisible(true);

}

public static void main(String []args)

{

new Slip4();

}
