Java 字符串和字符串数组如何进行比较

[申码程序]

package main;

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub 
	    Scanner in = new Scanner(System.in);  
	    String[] week= {"Monday","Tuesday","Wednesday",
	    		"Thursday","Friday","Saturday","Sunday"};//星期数组
	    System.out.println("请输入星期：");
	    String s=in.nextLine();//用户输入的星期；
	    boolean s1=true;
	    for (int i=0;i<week.length;i++)
	    {
	    	/*本人小菜鸟，对字符串的用法不太懂
	    	 * 重点是下边if语句怎么让字符串和字符串数组里的元素进行比较
	    	 * 还请各位大神指点迷津！
	    	 */
	    	if (s==(week[i]))
	    	{
	    		s1=true;
	    		break;
	    	}
	    }
	    if(s1)
	    {
	    	System.out.println(s);
	    }
	    else 
    	{
    		System.out.println("输入错误");
    	}
	}		
}

问题在代码的注释里。求大神解惑！

条件改成 week[i].equals(s) 也可以不用循环。

        System.out.println(Arrays.asList(week).contains(s));

[Royal_lr]

就楼上说的，s.equals(week[i]),不就好了吗

字符串得用.equals()方法，==比较的是地址值，.equals()方法比较的是字符串内容！

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

public class Demo {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String[] week= {"Monday","Tuesday","Wednesday",
                "Thursday","Friday","Saturday","Sunday"};//星期数组
        List<String> weekList = Arrays.asList(week);
        System.out.println("请输入星期：");
        String s=in.nextLine();//用户输入的星期；
        if(weekList.contains(s)){
            System.out.println(s);
        }
        else {
            System.out.println("输入错误");
        }
    }
}
