Do-While Loop
In java do-while loop is used to repeat the part of the program many times. If the number of repetition is not fixed and need to execute loop at least once.
In while loop, condition is evaluated before execution of loop’s body but in do-while loop condition evaluated after the execution of loop’s body.
Syntax
do{
statements(s);
} while(condition);

Example
public class DoWhileExample {
public static void main(String[] args) {
int i=1;
do{
System.out.println(i);
i++;
}while(i<=15);
}
}

Infinitive do-While Loop
In do-while loop if we pass true it will be infinitive do-while loop.
Syntax
do{
statement(s);
}while(true);
Example
public class DoWhileExample2 {
public static void main(String[] args) {
do{
System.out.println(“infinitive do while loop”);
}while(true);
}
}
Output
infinitive do while loop
infinitive do while loop
infinitive do while loop
