对一个数组（每项都是数值）求和，有哪些方法

Question

如题所述

Answer 1

import java.util.Scanner;

public class Test{

public static void main(String args[])
{Scanner sc = new Scanner(System.in);
System.out.println("输入数组的元素个数：");
int temp = sc.nextInt();
int a [] = new int[temp];
int[] b = new int[temp];
int []c=new int[temp];
System.out.println("输入第一个数组元素值：");
for (int i = 0; i < a.length; i++) {
a[i]= sc.nextInt();
}
System.out.println("输入第二个数组元素值：");
for (int i = 0; i < b.length; i++) {
b[i]= sc.nextInt();
}
System.out.print("第一个数组元素值：");
for (int i = 0; i < a.length; i++) {
System.out.print(a[i]+" ");
}
System.out.println();
System.out.print("第二个数组元素值：");
for (int i = 0; i < b.length; i++) {
System.out.print(b[i]+" ");
}
System.out.println();
System.out.print("两数组和：");
for (int i = 0; i < c.length; i++) {
c[i] = a[i]+b[i];
System.out.print(+c[i]+" ");
}

}
