Java for loop (sum of numbers + total)
提问by user2722931
I'm bit lost here. I have a forloop which increases a value, something like this:
我有点迷失在这里。我有一个for增加值的循环，如下所示：
int nu01 = 10000;
int level = 0;
int increase = 35000;
for (int i = 0; i < 100; i++) {
nu01 = nu01 + increase;
level++;
System.out.println(nu01);
if (level > 50) {
increase = 45000;
}
This works fine, but I need sum of all numbers from loop as total:
这工作正常，但我需要循环中所有数字的总和：
loop: 10,20,30,40,50,70,90,120.... total:10,30,60,100,150,220,310,430...
I tried:
我试过：
int total;
total=nu01 + nu01; //or nu01 + nu01 + increase;
But I get strange sums. So I need loop which increase numbers and sum of all those numbers. I hope this makes sense. Thanks.
但我得到了奇怪的数字。所以我需要循环来增加所有这些数字的数字和总和。我希望这是有道理的。谢谢。

what you want to do is something along the lines of
你想做的是类似的事情
int total = 0;
...
//beginning of your for loop
total = total + nu01; // alternatively you could do total += nu01;

I might be misunderstanding you here but I believe you want something like this
我可能在这里误解了你，但我相信你想要这样的东西
public class forLoops{
public static void main(String args[]){
//Initialisation
int level = 0;
int increase = 35000;
int total = 10000;
//For Loop
for(int i = 0; i < 100; i++){
total += increase; //Same as total = total + increase;
level++;
System.out.println(total);
if(level >= 50){
increase = 45000;
}
}
}
}

declare a total variable then store the tota int total =0;
声明一个total变量然后存储tota int total =0;
total += nu01;
总计 += nu01;
