1到100的递归累加

[student_2008]

用java实现了1-100的累加

	private static long count=1;
	private static long add(long num){
		long t=num;
		if(count>=1 && count<=100){
			t=t+count;
			count++;
			add(t);
		}else{
			return t;
		}
		return t;
	}
//调用
System.out.println(add(1));//打印的值是2...没明白

 private static long count=1;
    private static long add(long num){
        long t=num;
        if(count>=1 && count<=100){
            t=t+count;
            count++;
            t=add(t);//没测试，但是你这里原来肯定不对，而且下面的那个else{return ...}可以去掉
        }
        return t;
    }
//调用
System.out.println(add(1));//打印的值是2...没明白

值用个全局变量存放！

[JAVA_Xiu]

private static int n = 1;
private static long sum = 0;
public static long sumLong(int n){
if(n>0&&n<101){
sum+= n;
n++;
}
else return sum;
return sumLong(n);
}
//调用
System.out.println(sumLong(n));
