如何创建一个Java类，类似于C ++模板类？ [英] How to create a Java class, similar to a C++ template class?

问题描述

如何在Java中编写与此相当的内容？

  // C ++代码
 
模板类T> 
 class SomeClass 
 {
 private：
 T data; 
 
 public：
 SomeClass（）
 {
} 
 void set（T data_）
 {
 data = data_; 
} 
}; 
  
 
 
解决方案
 
  class SomeClass< ; T> {
 private T data; 
 
 public SomeClass（）{
} 
 
 public void set（T data_）{
 data = data_; 
} 
} 
  
您可能还想让类本身公开， 
 
 
 
 C ++模板和Java泛型之间还有其他的区别，但这些都不是你的例子的问题。
 
How do I write an equivalent of this in Java?
// C++ Code

template< class T >
class SomeClass
{
private:
  T data;

public:
  SomeClass()
  {
  }
  void set(T data_)
  {
    data = data_;
  }
};

解决方案
class SomeClass<T> {
  private T data;

  public SomeClass() {
  }

  public void set(T data_) {
    data = data_;
  }
}
You probably also want to make the class itself public, but that's pretty much the literal translation into Java.

There are other differences between C++ templates and Java generics, but none of those are issues for your example.
