Answer: The statement in the body of a while loop may never be executed if the loop condition is initially false. In contrast, the statements in the body of a do-while loop are always executed at least once, regardless of whether the loop condition is true or false.
In a while loop, the loop condition is evaluated before the first iteration of the loop, and if it is false, the loop body will never be executed. For example:
int i = 10;
while (i < 5) {
// This code will never be executed
System.out.println("i is less than 5");
}
In contrast, in a do-while loop, the loop body is executed at least once before the loop condition is evaluated. For example:
int i = 10;
do {
// This code will be executed once, even though the loop condition is false
System.out.println("i is less than 5");
} while (i < 5);
In the above example, even though the loop condition i < 5 is false, the loop body is executed once before the loop terminates.
