Java 中error: non-static variable count cannot be referenced from a static context 大多数时候,当我们尝试在 main 方法中使用非静态成员变量时,会出现error: non-static variable count cannot be referenced from a static context错误,因为main()方法是静态的并且是自动调用的。 我们不需要创建一个对象来调用m...
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...
public class MyClass { private int x; // non-static variable public static void main(String[] args) { System.out.println(x); // error: non-static variable x cannot be referenced from a static context } } To fix this error, you can either make the variable or method static, or ...
【情况二】:在静态方法中引用了一个实例变量 报错:Non-static variable 'instanceVariable' cannot be referenced from a static context 形如: 代码语言:javascript 复制 publicclassMyClass{privateString instanceVariable;publicvoidnonStaticMethod(){// 非静态方法实现,使用实例变量System.out.println(instanceVariable)...
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。
