java - 如何在类中使用方法或执行语句

Question

我不知道我是否需要更多咖啡，或者我的头很累，但是，我感觉自己像个白痴:)

我做错了什么？？？

我想调用类中的方法，但出现编译错误。

Compilation failure: Compilation failure:
java:[35,1] error: illegal start of type
java:[35,21] error: <identifier> expected
java:[35,22] error: ';' expected

我无法在类中执行此 block

//this is what doesn't work         
    if (custkey.contains(",")) {
        String[] ck = custkey.split(",");
        for ( String k : ck) {
            this.loadRefDb(k);
        } else {
            this.loadRefDb(custkey);
        }
    }

我的类(class)

也许是这个？ :)

if (custkey.contains(",")) {
    String[] ck = custkey.split(",");
    for ( String k : ck) {
        this.loadRefDb(k);
    } 
}else {
    this.loadRefDb(custkey);
}
