Scanner xxx = new Scanner(System.in);

然后xxx对象调用下列方法(函数),读取用户在命令行输入的各种数据类型:

next.Byte(),nextDouble(),nextFloat,nextInt(),nextLine(),nextLong(),nextShot()

package p3;import java.util.*;public class p3 {public static void main(String args[]){    Scanner a=new Scanner(System.in);    int b[];    b = new int[5];    for(int i=0;i<5;i++){        b[i] = a.nextInt();    }    int l=5;    while(l!=0){        --l;        System.out.printf("%d",b[l]);    }}}
