Question

java编程定义一个一维数组并赋值,求这个数组所有数值的和并输出.

Answer 1

public class Sum{

public static void main(String[] args) {

        int[] a={1,2,3,4,5,6,7,8,9};

        int sum=0;

        for(int i=0;i<a.length;++i){

                sum=sum+a[i];

                  }

        System.out.println(sum);

        }

}

Answer 2

int[] ints= new int[]{4,6,7,8,9,0,3,56,7,7};
int sum = 0;
for (int i = 0; i <ints.length ; i++) {
sum = sum+ints[i];
}
System.out.print("数组所有数之和为："+sum);
