创建一个带有string和trype对象的泛型

public class GenericClass<T> {
    private T genericMember;

    public GenericClass(T genericMember) {
        this.genericMember = genericMember;
    }

    public T getGenericMember() {
        return genericMember;
    }

    public void setGenericMember(T genericMember) {
        this.genericMember = genericMember;
    }
}

public class GenericMethod {
    public static <T> void printGeneric(T generic) {
        System.out.println(generic.toString());
    }
}

GenericClass<String> stringGeneric = new GenericClass<>("Hello");
System.out.println(stringGeneric.getGenericMember());  // 输出：Hello

GenericMethod.printGeneric(123);  // 输出：123
