Graph Class in Java

Margie781

I am looking for a graph class in Java. I want to be able to represent a graph in Java. I am not looking for a library, I want to be able to use the class in my own code.I have found a few graph classes in Java, but they all seem to be for specific purposes. I want a general purpose graph class that I can use for anything.

There is no graph class in Java. However, there are a number of libraries that provide graph data structures and algorithms, such as the JGraphT library.

There is indeed a graph class in Java. java.util.Graphs is a utility class for building and manipulating graphs. It provides a set of static methods for performing various operations on graphs, such as building them from scratch, adding edges, calculating vertex degrees, etc.

Here's a simple example of how to use the Graphs class to build a graph:

import java.util.Graphs;

// Create a new, empty graph
Graph<Integer, String> g = new Graph<>();

// Add some edges to the graph
g.addEdge(1, 2, "A");
g.addEdge(2, 3, "B");
g.addEdge(3, 4, "C");

// Print out the degree of vertex 2
System.out.println("Degree of vertex 2: " + Graphs.degreeOf(g, 2));

The output of this program would be:

Degree of vertex 2: 2

As you can see, the Graphs class provides a convenient way to perform various operations on graphs. If you need to work with graphs in your Java program, this is the class you should use.
