使用一个java类的变量到另一个java类

Question

java 类中有一个全局变量。这个变量从这个java类的函数中获取值。 我必须在另一个 java 类中使用这个变量及其值。

请检查以下代码：

Java class1：实用函数 Java 类 2：team.java 我想在 team.java 中使用的变量：search_project_id

我必须在 team.java 中使用变量的值：search_project_id，我必须将其作为 Web 应用程序中的字段的输入。

请帮忙。

提前致谢。

Answer 1

将变量声明为静态并通过类名引用在其他类中使用它，例如utilityFunctions.search_project_id

应该是这样的

public static String search_project_id;

使用“public”作为访问说明符使其可以在其他类中访问，而“Static”修饰符只维护变量的 1 个副本 使用该函数将一些值写入变量。稍后在其他课程中使用它。 注意：不要忘记在使用之前调用将值写入“search_project_id”的方法。
