The Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures. This means that methods within a class can have the same name if they have different parameter lists (there are some qualifications to this that will be discussed i...
(笔者注)Eclipse 中提示 "Erasure of method yourMethod(List<String>) is the same as another method in type YourExampleClass" 可变参数 String... str 和 String[] str 是相同的参数 (笔者注)Eclipse 提示 "Duplicate method" 注:对于类型擦除这一点,暂未找到Java语言规范的详细出处,待补充。 2、覆盖/...
