I want to break a while loop of the format below which has an if statement. If that if statement is true, the while loop also must break. Any help would be appreciated.
while(something.hasnext()) {
do something...
if(contains something to process){
do something
break if condition and while loop
}
}

You can't break out of if statement until the if is inside a loop. The behaviour of the break statement is well specified and, generally, well understood. An inexperienced coder may cause crashes though a lack of understanding in many ways. Misuse of the break statement isn't special.
Exit an if Statement With break in Python The break is a jump statement that can break out of a loop if a specific condition is satisfied. We can use the break statement inside an if statement in a loop. The main purpose of the break statement is to move the control flow of our program outside the current loop.
In the code above, you see a break in an if body. break can only exit out of an enclosing loop or an enclosing switch statement (same idea as an enclosing loop, but it's a switch statement). If a break statement appears in an if body, just ignore the if.
The break keyword does exactly that. Here is a contrived example:
public static void main(String[] args) {
int i = 0;
while (i++ < 10) {
if (i == 5) break;
}
System.out.println(i); //prints 5
}
If you were actually using nested loops, you would be able to use labels.

An "if" is not a loop. Just use the break inside the "if" and it will break out of the "while".
If you ever need to use genuine nested loops, Java has the concept of a labeled break. You can put a label before a loop, and then use the name of the label is the argument to break. It will break outside of the labeled loop.
