为什么这只生成一个随机字符串？ 【JAVA]

Question

public class TavernNameGen {

private static final String TXT_PLACE_NAME  = buildingText();
private static final String TXT_VERBING     = verbText();

private static final String NAME =

当我运行它时，它会为酒馆名称生成一个字符串。我的问题是，当我在我的程序中运行它时，它只会在我再次编译程序时生成一个新的字符串。如果我退出程序并再次运行它，它将生成相同的字符串。 我在这里错过了什么？ 该类仅通过命令TavernNameGen.read（）;

从一个外部类执行

您已声明变量static。这意味着它们在对过程的调用之间保留它们的值，并且初始化（通过调用verbText（）等仅在第一次调用方法时完成ONCE。删除static它应该工作如你所料。
