Instantiating generics type in java

by 
public class Abc<T> {
    public T getInstanceOfT(Class<T> aClass) {
       return aClass.newInstance();
    }
}

You’ll have to add exception handling.

You have to pass the actual type at runtime, since it is not part of the byte code after compilation, so there is no way to know it without explicitly providing it.
