How do you write two while loops in Java?
Consider the code snippet of a nested while loop: class NestedWhileLoop { public static void main(String args[]) {…The inner loop starts just after the while statement of the outer loop:
- int innerLoop = 3;
- while(innerLoop < 6) {
- System. out. println(outerLoop + “:” + innerLoop);
- innerLoop++;
- }
Can a while loop have two conditions Java?
As seen on line 4 the while loop has two conditions, one using the AND operator and the other using the OR operator. Note: The AND condition must be fulfilled for the loop to run. However, if either of the conditions on the OR side of the operator returns true , the loop will run.
How do you repeat a while loop in Java?
You create the while loop with the reserved word while, followed by a condition in parentheses ( ) Within the curly brackets, { }, you specify all operations that you want to execute as long as the condition is true. The loop repeats itself until the condition is no longer met, that is, false.
Can we use && in while loop?
Suppose in a while loop, you have two conditions, and any one needs to be true to proceed to the body, then in that case you can use the || operator between those two conditions, and in case you want both to be true, you can use && operator.
Can we use two conditions in for loop?
It do says that only one condition is allowed in a for loop, however you can add multiple conditions in for loop by using logical operators to connect them.
How do you repeat a while loop?
In programming, loops are used to repeat a block of code….Example 3: repeat… while Loop.
| Variable | Condition: i <= n | Action |
|---|---|---|
| i = 4 n = 5 | true | 4 is printed. i is increased to 5. |
| i = 5 n = 5 | true | 5 is printed. i is increased to 6. |
| i = 6 n = 5 | false | The loop is terminated. |
What is do while loop in Java?
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.
Do while loops repeat?
Contrast with the while loop, which tests the condition before the code within the block is executed, the do-while loop is an exit-condition loop. This means that the code must always be executed first and then the expression or test condition is evaluated. If it is true, the code executes the body of the loop again.
What is a do while loop example in real life?
Real World Example, Go to the bath room: DO { Check_Door_Lock(); } WHILE (WAIT_WHILE_DOOR_IS_LOCKED()); after the loop is done then the WAIT_WHILE_DOOR_IS_LOCKED() has returned a false value, so it isn’t locked anymore, thus, the whole loop ends.
