如何创建类似于C++模板类的Java类？

public class MyGenericClass<T> {
    private T data;

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

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }
}

MyGenericClass<Integer> integerClass = new MyGenericClass<>(5);
MyGenericClass<String> stringClass = new MyGenericClass<>("Hello, World!");

public class MyGenericClass<T, U> {
    private T data1;
    private U data2;

    public MyGenericClass(T data1, U data2) {
        this.data1 = data1;
        this.data2 = data2;
    }

    // 其他方法和属性
}
