【情况一】:在静态方法中引用了一个非静态方法 报错:Non-static method 'xxx()' cannot be referenced from a static context 形如: 代码语言:javascript 代码运行次数:0 publicclassMyClass{publicvoidnonStaticMethod(){// 非静态方法实现}publicstaticvoidstaticMethod(){// 在静态方法中引用非静态方法,会导致错...
Methods like Trim(), ToUpper() or Split() are non-static methods because they access the internal state of the object even though they don’t change it. But the Compare() method, on the other hand, is a typical static method. Compare() operates on two separate strings passed in as ...
在静态方法(static method)中访问非静态(non-static)的数据(data) 如果你新建了一个窗体,上面加了一个Lable,id=lbl,如果想使用方法(method)更改lbl的显示的值,可以这样做: publicvoidChangeText() { lbl.Text="Changed"; } 调用ChangeText(),lbl就会显示为“Changed”。 如果需要把ChangeText()改为静态方法, ...

在使用Lambda表达式时,如果尝试调用非静态方法,而该方法又不能在静态上下文中被引用,就会遇到“Non-static method cannot be referenced from a static context”的错误。为了解决这个问题,我们需要理解Lambda表达式和静态方法的区别,并采取相应的解决方法。
Use static methods only if the method dependsONLY ON ITS PARAMETERS. If you're reading from the config, making database calls or communicating with an outside resource in any way use an instance method. Seriously, the performance difference between a static and non-static method is so small ...
A non-static method in Java belongs to the object of a class and is like the paper pattern made from the blue print or original dress. To create a static method in Java, you prefix the key word 'static' before the name of the method. A static method belongs to the class, and ...
