Question

哪位高手能帮我写一个java小程序,1+3+5+7+....+100,用FOR语句写!

Answer 1

int Sum = 0;
for(int i = 1;i <= 100; i++)
Sum += i;
System.out.println("总和："+ Sum);
放到你的MAIN里面就行了

Answer 2

注意看好，楼主的是奇数!!!
public static void main(String[] args) {
int j =0;
for(int i=1;i<100;i+=2){
j+=i;
System.out.println(i);
}
j+=100;
System.out.println(j);
}

Answer 3

public class Add
{
public int add(){
int sum=0;
for(int i=1;i<=100;i+=2){
sum+=i;
}
return sum+100;
}
public static void main(String[] args)
{
Add add=new Add();
int result=add.add();
System.out.println("The sum is "+result);
}
}

Answer 4

是不是加到99啊？
int sum = 0;
for(int i = 0; i <= 50; i++)
{
sum += 2 * i - 1;
}

Answer 5

注意，最后一个数是100
