错误显示为：“语法错误，插入”）“完成MethodDeclaration”

为什么我在创建图形实例后无法访问该方法？

Answer 1

在Java中，您的代码语句应该是某些方法或块

的一部分

在你的情况下，至少是main方法，如果那是你的主要类。

代码不能只是在类体内部，在任何块之外

以下代码可能有助于您实现的目标

public class prims {

    public static void main(String args[]) {
        Graph g=new Graph();

        g.generateGraph(10,20); // Error here
    }

}

Java：无法访问其他类的方法
