What does <> mean for java generics?

Question

I have a bit of code:

class MyClass 
  private List allPreExistingConfigsForCodes() {
    if(this.allCodesForThisType.size() == 0)
             


        

Answer 1

From the Java Tutorials generics lesson:

In Java SE 7 and later, you can replace the type arguments required to invoke the constructor of a generic class with an empty set of type arguments (<>) as long as the compiler can determine, or infer, the type arguments from the context. This pair of angle brackets, <>, is informally called the diamond. For example, you can create an instance of Box with the following statement:

Box integerBox = new Box<>();
