Therefore, use a while-true loop with a break in the loop body to avoid duplicate code and to match your intuition that the loop is a read-and-process loop. When the continue command is met, the Java Virtual Machine jumps to the next iteration of the loop without executing more of the while loop body. There are several ways to terminate a for loop early, so you only need to know the maximum times you intend to iterate around the loop. Code is from C++ language. This means the nested while loop will finish slower, given the same number of computations to perform, compared to the nested for loop.
