Loop Control In Java
Previous Home Next

In Java there are control structures that let you repeat statements. Such control structures are called Loops. Loops can be further categorised as :

  1. Indeterminate Loops

  2. Determinate Loops

Indeterminate Loops

Loops in which you do not know how many times a loop should be processed are called Indeterminate loops. Two types of indeterminate loops are following as under :

Firstly there is the while loop that only executes the body of the loop while a condition is true. Its general form is:


while (condition)
 {
  statement1;
  statement2;
 }

The while loop will never execute if the condition is false. Its structure is quite very similar to other languages like C and C++.

 

Secondly there is the do-while loop that executes the body of the loop at least once irrespective of the condition is true or false. Just like other languages it has the following form :


 do
{
statement1;
statement2;
}while(condition);

Determinate Loops

The for loop is a very common construct to support iteration that is controlled by a counter or similar variable that is updated after every iteration. Like other languages it has the form :


 for(int j=0; j<10; j++)
{
  System.out.println(j);
}

The above program prints numbers from 0-9.

In general, the first slot of the for loop contains the counter initialization, second for testing the condition given and the last one is for updating the counter. Java like C, allows almost any expression in the various slots of a for loop, but it's an unwritten rule that the three slots of a for statement should only initialize, test, and update the same counter variable.
