调用类型参数的方法

public class MyClass<T> {
    private T data;

    public MyClass(T data) {
        this.data = data;
    }

    public T getData() {
        return data;
    }
}

MyClass<Integer> integerMyClass = new MyClass<>(10);
MyClass<String> stringMyClass = new MyClass<>("Hello World");

public T MyMethod<T>(T input) {
    // Do something with input
    return input;
}

int result1 = MyMethod<int>(10);
string result2 = MyMethod<string>("Hello World");
