Java7 switch新特性

在Java7之前，switch只能匹配整数值，和字符；而Java7添加了字符串的匹配特性。

代码如下：

package blog;


public class Main {
    public static void show(String str) {
        switch (str) {
            case "people":
                System.out.println("Input string is people");
                break;
            case "school":
                System.out.println("Input string is school");
                break;
            case "bird":
                System.out.println("Input string is bird");
                break;
            default:
                System.out.println("Others");
        }
    }
    
    public static void main(String[] args) {
        show("people");
        show("bird");
        show("dfkdf");
    }
}
