Loop: In computer programming, a loop is a sequence of instruction s that is continually repeated until a certain condition is reached.
Java programming language provides the following types of loop to handle looping requirements. Click the following links to check their detail.
Loop Type | Description |
while loop | Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. |
for loop | Execute a sequence of statements multiple times and abbreviates the code that manages the loop variable. |
do-while loop | Like a while statement, except that it tests the condition at the end of the loop body |
How can we justify which loop is best for over programs.
For loop: use when the specific end point is available.
While loop: use when the specific end point is not available.
Do-while loop: use when the specific end point is not available. But loop must run at once whether condition is true or false.
