Write a java program to demonstrate a simple while loop. We use a while loop in a program when we know the exit condition and not sure how many times to loop the iterations.\u00a0 The loop will be executed until the loop expression is true.<\/p>\r\n
There is another variation of the loop called the do-while loop. Do-while will loop at-least once before evaluating the loop condition.<\/p>\r\n
while (expression)<\/strong><\/p>\r\n {<\/strong><\/p>\r\n \u00a0 \u00a0 \u00a0 \u00a0 \/\/statements(s)<\/strong><\/p>\r\n }<\/strong><\/p>\r\n <\/p>\r\n For example, we want to exit the loop when the count reaches 10.\u00a0 Below is a simple Java program to make use of the while loop.<\/p>\r\n The while loop will be executed 10 times and the loop is exited when count reaches 11.<\/p>\r\n Count is :1 —<\/p>\r\n Java Tutorial on this website:<\/p>\r\nJava Program<\/h3>\r\n
