Question

请编写一个Java程序,能够求出0-100之间的偶数和

Answer 1

　　代码如下：

public class Math{
   public static void main (Stting args[]){
      int i=0;
      int m=0;
      while (i<=100){
        if(i%2=0){
          m=m+i;
        }
        i=i+1;
         
      }
      System.out.println("0-100之间偶数和为"+m);
      
   }
}

Answer 2

现给你写一个
public class chen{
public static void main(String args[]){
int sum=0;
for(int i=0;i<=100;i=i+2)
sum+=i;
System.out.pritnln("sum=",sum);
}
}

Answer 3

sum=0;
for(int i=2;i<=100;i+=2){
sum+=i;
}
System.out.println(sum);

Answer 4

public
static
void
main(string[]
args)
{
int
sum
=
0;
for
(int
i
=
0;
i
<=
100;
i++)
{
if(i%2==0){
sum
+=
i;
system.out.print(i+"
");
system.out.print("偶数和为："+sum);
}
}
}
如果不要0
i初始值给1就可以了
希望能帮到你！

Answer 5

public class Sum {

public static void main(String[] args) {
Sum sum = new Sum();
System.out.println("0-100之间偶数和：" + sum.getEvenSum());
}

private int getEvenSum(){
int sum = 0;
for(int i = 0; i <= 100; i=i+2){
sum += i;
}
return sum;
}
}
