How to create a Java class, similar to a C++ template class?

Question

How do I write an equivalent of this in Java?

// C++ Code

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

public:
  SomeClass()
  {
  }
  vo         


        

Answer 1

class SomeClass {
  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.
