- In the Java programming language, write a program that opens a 400x200 window with two 200x200 buttons. One button says "Close" - which closes the program, and on the other the number "16". Each time you press this button, the number is halved until 1. When 1 is reached the button does not change anymore.JavaPLEASE DO IT IN JAVA!! Create a Palindrome application that prompts the user for a string and then displays a messageindicating whether or not the string is a palindrome. A palindrome is a word or phrase that isspelled the same backwards and forwards. For example, “mom” is a palindrome, as well as “kayak”and “Never odd or even”.
- Computer Science A Java swing program that lets the user draw a line that can be individually deleted or moved. make a JPanel to allow users to draw a line with their mouse, move the line to wherever, and delete each individual line chosen by the user. Use JRadioButton and/or JComboBox in a separate JPanel to allow users to choose to draw, move, or delete a line. The user should be able to have multiple lines at once Whenever necessary, the user should be prompted with instructions on how to continue or what is wrong. (For example; conformation prompt for deleting a line, or which line the user wants to delete)In Java only--Java Applets Create an applet that will draw a set of ovals and the user should be able to specify the number of ovals.

- Java Use GUI. Simple text editor Copy / Cut Paste Display number of characters (with spaces / without spaces) Display number of words Display number of linesOne interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For ex- ample, if your program reads the number 7, it should output HTML5 text that displays *******.Using the Java programming language write a program that takes an email address as an input from the keyboard and, using a loop, steps through every character looking for an @ sign.

So the mouse point becomes the center of the rectangle.Using Javascript and HTML: An interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For example, if your program reads the number 5, it should out HTML5 test that displays *****.Create two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. Using Java compiler.
