Java 编程练习：比较两个花名册

package step1;

import java.util.Arrays; import java.util.Scanner;

public class Roster { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String[] roster1 = scanner.nextLine().split(" "); String[] roster2 = scanner.nextLine().split(" "); /********** Begin / System.out.println(roster1.length); System.out.println(roster2.length); if (Arrays.equals(roster1, roster2)) { System.out.println('相同'); } else { System.out.println('不相同'); } /* End *********/ } }
