JAVA第三周作业(从键盘输入若干数求和) 在新的一周,我学习了JAVA的IO编程.下面的代码实现了从键盘输入若干数求和的目标.import java.util.Scanner; public class sum{ public static void main(String[] args) {// TODO Auto-generated method stub//从键盘输入若干整数并求和输出int nextValue;int sum=0;Scanner r = new Scanner(Syst
package test; import java.util.Scanner; //判断输入的数是不是素数 public class Test18 { public static void main(String[] args) { Scanner s = new Scanner(System.in); System.out.println("输入判断的数"); int a = s.nextInt(); for(int i=2 ; i<=a;i++){ //最小的素数是2 if(
