Notice how the method declares a generic type T for the Class parameter, as well as for the return type of the method. This signals to the Java compiler that the return type of the method should be of the type of the Class object passed in. Thus, if you call with String.class - th...
Explanation: In the above exercise, we define a generic method mergeLists() that takes two lists list1 and list2 as input. The method creates a newly created mergedList from an ArrayList. It iterates up to the maximum length of the two lists using a for loop. In each iteration, it ch...
Generic methods allow type parameters to be used to express dependencies among the types of one or more arguments to a method and/or its return type. If there isn't such a dependency, a generic method should not be used.It is possible to use both generic methods and wildcards in tandem...
The syntax for a generic method includes a list of type parameters, inside angle brackets, which appears before the method's return type. For static generic methods, the type parameter section must appear before the method's return type. TheUtilclass includes a generic method,compare, which com...

Generic Method:Generic Java method takes a parameter and returns some value after performing a task. It is exactly like a normal function, however, a generic method has type parameters that are cited by actual type. This allows the generic method to be used in a more general way. The compi...

泛型类(generic class)就是有一个或多个类型变量的类。例如下面的 Pair 类,就有两个类型变量,分别是 T 和 U: public class Pair<T, U> { public T first; public U second; public Pair(T first, U second) { this.first = first; this.second = second; ...
