笔记

public class Demo04Var{
	public static void main(String[] args){
		int num1 = 10;
		int num2 = 3;
		
		int sum = num1+num2;
		System.out.println(sum);//13
		
		int sub = num1-num2;
		System.out.println(sub);//7
		
		//System.out.println(num1*num2);//30
		int mul = num1*num2;
		System.out.println(mul);//30
		
		/*
		  由于/前后都是整数,结果取整数部分,结果还赋值给一个整数变量
		*/
		int div = num1/num2;
		System.out.println(div);//3
		
		double div1 = num1/num2;//3.0
		System.out.println(div1);
	}
