java小作业(一)

1.两个变量值交换

public static void main(String[] args) {
		// TODO Auto-generated method stub
		int a = 10;
		int b = 20;
		int c = a;
		a = b;
		b = c;
		System.out.println("a="+a+",b="+b);
	}

2.求出153的各个位数的值

public static void main(String[] args) {
		// TODO Auto-generated method stub
		int a = 153;		
		int bai = a/100;
		int shi = a%100/10;
		int ge = a%10;		
		System.out.println("百位:"+bai+"，十位："+shi+"，个位："+ge);
		
	}
