How do you declare a generic method in Java?Question 12Answera.<T> returnType methodName(T arg)b.returnType methodName<T>(T arg)c.returnType<T> methodName(T arg)d.<T> methodName(returnType arg)
Solution
The correct way to declare a generic method in Java is option a.
Here is the step by step process:
-
First, you need to declare the type parameter within angle brackets before the return type of the method. This indicates that the method will be dealing with generics. In this case, it is
<T>. -
Then, you specify the return type of the method. It can be any valid data type in Java. In this case, it is
returnType. -
After that, you write the method name. It can be any valid identifier in Java. In this case, it is
methodName. -
Finally, you declare the method parameters inside the parentheses. The type of the parameter is the same as the type parameter declared before the return type. In this case, it is
(T arg).
So, the correct format is: <T> returnType methodName(T arg).
