1. Write a while loop that verifies that the user enters a negative integer value.
2. Write a code fragment that reads and prints integer values entered by a user until a particular sentinel value (stored in SENTINEL) is entered. Do not print the sentinel value.

Use a for-loop to draw the stripes. Do not try to draw any stars in the blue square. (import javax.swing.JApplet; and java.awt.*; ) (public class Flag extends JApplet)
5. String s1 is said to overlap String s2 if all of the characters in s1 also appear in s2. Write a set of code that will set the Boolean variable overlap to true if s1 and false otherwise. Assume both s1 and s2 have already been input.
