[投稿123] groovy 置入行銷版
依舊是 Output123
public class Output123 {
public static void main(String[] args) {
char[] ch = new char[]{1,2,3};
System.out.println(String.valueOf(ch));
}
}
1. 先把它 compile 好
2. 寫一個 Main.groovy
qty:project123_groovy_mixin qrtt1$ cat Main.groovy
Output123.metaClass.'static'.main = {
System.out.println "123"
}
Output123.main()
用 metaClass 改掉 main 的實作 :P
3. 執行 Main.groovy
qty:project123_groovy_mixin qrtt1$ groovy Main.groovy
123
PS. groovy 很有趣，快來寫 groovy。
