Erasure of type parameters in Generic Method arguments
The Java compiler erases type parameters in generic method arguments. Let us consider the following example to demonstrate two things:
- To demonstrate erasure of type parameters in generic method arguments
- To count number of occurrences of an element in an array
IGenericMethod.java:
GenericMethodImpl.java:
GenericMethodTest.java:
Output:
Number of occurences of element one in an array is: 3
Compile the above source code and inspect using javap command as shown in the picture below. See what Java Compiler has done.
