通过键盘输入值数值进行对比

package test1;

import java.util.Scanner;

public class Input {
	public static void main(String[] args) {
		Scanner sca = new Scanner(System.in);
		System.out.println("请输入对应的字符");
		String str = sca.next();
		if (str.equals("hello")){
			System.out.println("Hello World!!!");
		}
	}
}
