代码 publicclassMyClass{publicvoidnonStaticMethod(){// 非静态方法实现}publicstaticvoidstaticMethod(){// 在静态方法中引用非静态方法,会导致错误nonStaticMethod();// 错误:Non-static method 'nonStaticMethod()' cannot be referenced from a static context}} 解决这个问题的方法是,要么将非静态方法改为静态方...
Non-static method 'xxx()' cannot be referenced from a static context 形如: public class MyClass { public void nonStaticMethod() { // 非静态方法实现 } public static void staticMethod() { // 在静态方法中引用非静态方法,会导致错误 nonStaticMethod(); // 错误:Non-static method 'nonStaticMethod...
可以的。类可以有内部类，具体问题。具体再追问。错误提示是说：非静态变量类型不能在静态上下文中引用。（1）你的；main方法是static的，即静态的。（2）如果你将类包含在里面的话，需要将printchar声明为静态的。才能在main方法中引用。首先楼上说的有歧义，如果在static方法中new 一个对象都不行的...

The error "Non-static variable cannot be referenced from a static context" occurs when attempting to access a non-static variable or method from a static context, such as within a static method. In Java, static methods are class-level and do not have access to instance-specific variables or...
There are a variety of reasons to use Java's nested classes both static and non-static. First, nested classes and nested interfaces allow types to be structured and scoped into logically related groups. If a class is useful to only one other class, then it is logical to embed it in ...
1.static是一个修饰符,用于修饰成员; 2.static修饰的成员被所有的对象所共享; 3.static优先于对象存在,因为static的成员随着类的加载就已经存在了; 4.static修饰的成员多了一种调用方式,就可以直接被类名所调用。(类名.静态成员) 5.static修饰的数据是共享数据,对象中存储的是特有数据; ...
