根据模板的类型使类成员变量成为可选的非冗长解决方案？

public class TemplateClass<T> {
    private T memberVariable;

    public TemplateClass(T memberVariable) {
        this.memberVariable = memberVariable;
    }

    public T getMemberVariable() {
        return memberVariable;
    }

    public void setMemberVariable(T memberVariable) {
        this.memberVariable = memberVariable;
    }
}

TemplateClass<String> stringTemplate = new TemplateClass<>("Hello");
System.out.println(stringTemplate.getMemberVariable());  // 输出：Hello

TemplateClass<Integer> integerTemplate = new TemplateClass<>(123);
System.out.println(integerTemplate.getMemberVariable());  // 输出：123
