public class Label {
public static void main(String[] args) {
outer:
for (int i = 0; i < 4; ++i) {
for (int j = 0; j < 4; ++j) {
System.out.println("i: " + i + ", j: " + j);
if (i + j == 2)
continue outer;
if (i + j == 4)
break outer;
}
}
}
}

帮我解释这句是什么意思 System.out.println("i: " + i + ", j: " + j);

System.out.println("i:"+i+",j:"+j+",k:"+k);//输出 i:2,j:3,k:4
这句中的"+i+"是不是等于"i"或者"+i"或者"k+"
