Java循环语句入门解析：轻松掌握for与while，避免无限循环陷阱

for (初始化; 条件判断; 迭代操作) {

// 循环体

}

int[] scores = {85, 92, 78, 90, 88}; int sum = 0; for (int i = 0; i < scores.length; i++) {

sum += scores[i];

} double average = (double) sum / scores.length;

// 危险的写法 int i = 0; while (i < 10) {

System.out.println(i);
// 忘记 i++ 就会导致无限循环

}
