[Java] 蓝桥杯ADV-95 算法提高字符串比较

独立实现标准字符串库的strcmp函数，即字符串比较函数，从键盘输入两个字符串，按字典序比较大小，前者大于后者输出1，前者小于后者输出-1，两者相等输出0。
样例输入:
apple one
样例输出:
-1
样例输入:
hello he
样例输出:
1
样例输入:
hello hello
样例输出:
0

package adv95;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String a = in.next();
        String b = in.next();
        in.close();
        if (a.compareTo(b) < 0) { System.out.println("-1"); } else if (a.compareTo(b) > 0) {
            System.out.println(1);
        } else {
            System.out.println(0);
        }
    }

}

package adv95;

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

String a = in.next();

String b = in.next();

in.close();

if (a.compareTo(b) < 0) { System.out.println("-1"); } else if (a.compareTo(b) > 0) {

System.out.println(1);

} else {

System.out.println(0);

}
