如何在不两次初始化布尔值的情况下使用while循环条件？

Question

What is the best way to simply this expression so that I don't have to set colFinished twice? (colFinished has to be reset to false in each run of the outer loop)

boolean colFinished = false;
    for (int c = 0; c < SIZE; c += 1) {
        colFinished = false;
        while (!colFinished) {
            for (int r = 1; r < SIZE; r++) {
            ...

Answer 1

If you have no use of colFinished outside the for loop, try :

for (int c = 0; c < SIZE; c += 1) {
    boolean colFinished = false;
    ...............

Else I think there is no other way.

Answer 2

You can declare your variable inside the first for-loop:

for (int c = 0; c < SIZE; c += 1) {
    boolean colFinished = false;
    while (!colFinished) {
        for (int r = 1; r < SIZE; r++) {
        ...
