Loop In Java
In programming languages, loops are used to execute a set of instructions/functions repeatedly when some conditions become true.
A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages
There are three types of loops in java.
- for loop
- while loop
- do-while loop
| S.No. | Loop & Description |
|---|---|
| 1 | for loop
Execute a sequence of statements multiple times and abbreviates the code that manages the loop variable. |
| 2 | while loop
Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. |
| 3 | do...while loop
Like a while statement, except that it tests the condition at the end of the loop body. |
Loop Control Statements
Loop control statements change execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed.
- break statement
- continue statement
| S.No. | Control Statement & Description |
|---|---|
| 1 | break statement
Terminates the loop or switch statement and transfers execution to the statement immediately following the loop or switch. |
| 2 | continue statement
Causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating. |
