Java一些小例子

package com.example.demo;

public class Solution {

    public static void main(String[] args) {
        func();
    }

    private static int func() {
        try {
            System.out.println("in try");
            return func2("try return");
        } finally {
            System.out.println("in finally");
            return func2("finally return");
        }
    }

    private static int func2(String input) {
        System.out.println(input);
        return 1;
    }
}

打印：

package com.example.demo;

public class Solution {
    public static void main(String[] args) {
        String a = "123";
        String b = "123";
        System.out.println(a == b);
        String c = new String("123");
        System.out.println(a == c);
    }
}
