Now, it continues the execution of the inner while loop completely until the condition j>=5 returns false. And you do that minimally by putting additional parentheses as a grouping operator around the assignment: But the real best practice is to go a step further and make the code even more clear by adding a comparison operator to turn the condition into an explicit comparison: Along with preventing any warnings in IDEs and code-linting tools, what that code is actually doing will be much more obvious to anybody coming along later who needs to read and understand it or modify it. Java while loop with Examples - GeeksforGeeks While using W3Schools, you agree to have read and accepted our. If the user enters the wrong number, they should be promoted to try again.
