谁可以写出用java计算1-100整数的累加和的代码？

谁可以写出用java计算1-100整数的累加和的代码，并显示每个整数和当前累加和的对应关系

Answer 1

int j = 0;
int sum = 0;
for(int i=1; i<=100; i++) {
j=i+1;
sum += i;
System.out.println(sum + " + " + j + " = " + (sum+j));
}

Answer 2

int sum=0,num=0;
for (int i = 1; i <= 100; i++) {
num=i;
System.out.println(sum+"+"+num);
sum+=num;

}
System.out.println(sum);

Answer 3

public class Test {
public static void main(String[] args) {

int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("The result is:" + sum);
}

}

out:
The result is:5050

Answer 4

int sum=0;
for (int i = 1; i <= 100; i++) {
sum=sum+i;
}
System.out.print(sum);
