It does not affect the loop enclosing the switch. The second use, to forcibly terminate the loop and resume at next statement of the loop. As soon as, the break statement is encountered inside the loop, that loop is immediately terminated without executing the remaining code in the body of that loop, and the program control reaches to next statement written after that loop. If the break is used with a nested loop, it breaks out only the innermost loop and does not affect the outer loop.
The third use, using the break as the form of goto. As goto provides an unstructured branching which is hard to understand and also goto prohibits compiler optimization. Java uses an expanded form of break which is similar as goto and helps to exit more than one block at a time and resume the control of the program to the end of labeled block, mentioned with the break statement. The labelled break statement is used to exit from the set of nested loop.
As the labelled break statement is encountered, the control exits the labelled block, which is mentioned with the break statement. In this code, as the control reaches the third block, its print statement gets executed. The break statement will exist in python to get exit or break for and while conditional loop. The break and continue can alter flow of normal loops and iterate over the block of code until test expression is false.
The break is used to terminate the execution of the statements and iteration of the loop. It will move to the next statement after the loop and continue for different purposes.
The break statement will allow control to move out of loop skipping the execution of the remaining statements of loop and continue will allow the control to remain inside the loop by moving 1 iteration ahead.
The important things that need to keep regarding use of continue and break used with the loops. The break statement will cause the jump statements and break statement to cause the termination or exit the loop for early of the loop. The break statement is nested loop and allows the innermost loop and the control will remain inside outermost loop inside the nested loop will allow skip of current location and execution of next iteration of innermost loop.

You assign variable that is not used anywhere. Suggested edit was more readable. Hinek Hinek 9, 12 12 gold badges 50 50 silver badges 71 71 bronze badges. Omeid I agree, that it's tricky This is a great example! Great example. BREAK: break ends execution of the current for, foreach, while, do-while or switch structure.
What I understand from this is that break will exit current looping structure and will keep running outer loop code. Continue will make loop get back to evaluation, and will iterate over itself until it evaluates to false.
Break 2 will exit 2 levels, which in this case will stop the iteration altogether. Continue 2 will evaluate not the current loop level 1 so to speak , but the outer loop in this case. The continue statement breaks one iteration in the loop , if a specified condition occurs, and continues with the next iteration in the loop.
If you use a incrementing value in your loop, be sure to increment it before calling continue; or you might get an infinite loop. In the same way that one can append a number to the end of a break statement to indicate the "loop" level upon which one wishes to 'break' , one can append a number to the end of a 'continue' statement to acheive the same goal. The most basic example that print "13", skipping over 2.
