算术运算符除号：/

java除号：/ 的使用

public class Fighting{
	public static void main(String[] args){
	int num1 = 7;
	int num2 = 5;
	int result = num1/num2;
	double result2 = num1/(double)num2;//结果保留double
	double result3 = num1/(num2+0.0);//(num2+0.0)结果保留double型
	double result4 = num1/num2+0.0;//num1/num2结果为int +0.0 ）结果为double
	
	System.out.println("num1/num2 = "+result);
	System.out.println("num1/(double)num2 = "+result2);
	System.out.println("num1/(num2+0.0) = "+result3);
	System.out.println("num1/num2+0.0 = "+result4);
	
	System.out.println("-7/5 = "+(-7/5));
	System.out.println("7/-5 = "+(7/-5));
	System.out.println("-7/-5 = "+(-7/-5));
	}
