一道有趣的面试题（自创）

public static void main(String[] args) {
setValue();// 1
setValue2();// 100
}

static void setValue() {
int[] i = new int[1];
i[0] = 100;
setA(i);
System.out.println(i[0]);
}

static void setValue2() {
int i = 100;
setA(i);
System.out.println(i);
}

////
static void setA(int[] x) {
x[0] = 1;
}

static void setA(int x) {
x = 1;
}
