调用setGlobalVariable方法将值10设定给全局变量globalVariable。 调用printGlobalVariable方法打印全局变量的值,输出结果为Global Variable: 10。 通过以上步骤,我们成功实现了将set方法指定的值设定为全局变量,在类的其他方法中都能访问到该值。 总结 在Java中,要将set方法指定的值设定为全局变量,我们需要定义一个成员变...
在setGlobalVariable方法中,我们将参数的值赋给globalVariable全局变量。 将局部变量赋给全局变量后,通过方法调用来访问全局变量 另一种方法是将局部变量的值直接赋给全局变量,并通过方法调用来访问全局变量。 publicclassExample{privateintglobalVariable;publicvoidsetGlobalVariable(intvalue){this.globalVariable=value;}p...
许多编程语言都具有用于声明全局变量的特殊语法,例如,Python使我们可以使用global关键字: global a_variable = 5 C通过简单地在函数外部声明变量来创建全局变量。 int aVariable = 3; int someFunction() { print(aVariable); } 无论创建全局变量的语法如何,它们的工作方式大致相同。它们允许您从任何其他类或函数...

> global variable: similar to Java "static public" variable. A global variable can be constant or modifiable denoted by the final field. A global variable has a name, a value and an alias. The value could be a general expression such as pi/4 where pi is another constant variable....
