Example: Iterating array using do-while loop
Here we have an integer array and we are iterating the array and displaying each element using do-while loop.
class DoWhileLoopExample2 {
public static void main(String args[]){
int arr[]={2,11,45,9};
//i starts with 0 as array index starts with 0
int i=0;
do{
System.out.println(arr[i]);
i++;
}while(i<4);
}
}
Output:
2
11
45

Answer:
do-while loop in Java with examples
In the last tutorial, we discussed while loop. In this tutorial we will discuss do-while loop in java. do-while loop is similar to while loop, however there is a difference between them: In while loop, condition is evaluated before the execution of loop’s body but in do-while loop condition is evaluated after the execution of loop’s body.
