Introduction to the Method "public static boolean routeExists"

The "public static boolean routeExists" method is a Java function that can be used to determine if there is a route between two points in a given graph. The method takes in two parameters: the starting node and the destination node. It returns a boolean value: "true" if there is a route between the two nodes, and "false" if there is not.

Syntax

The syntax for this method is as follows:

public static boolean routeExists(GraphNode startNode, GraphNode endNode)

The method takes in two GraphNode objects as arguments: the start node and end node. It returns a boolean value: "true" if there is a route between the two nodes, and "false" if there is not.

Parameters

• startNode: The starting node in the graph.
• endNode: The destination node in the graph.

Return Value

The method returns a boolean value: "true" if there is a route between the startNode and endNode, and "false" if there is not.

Example Usage

Here is an example of how to use the "public static boolean routeExists" method:

GraphNode startNode = new GraphNode();
GraphNode endNode = new GraphNode();
boolean hasRoute = routeExists(startNode, endNode);

In this example, we create two GraphNode objects, startNode and endNode, and then we call the routeExists method with these objects as arguments. The method returns a boolean value that we store in the hasRoute variable.

Conclusion

The "public static boolean routeExists" method is a useful tool for determining if there is a route between two points in a graph. It takes in two GraphNode objects as arguments and returns a boolean value indicating whether or not there is a route between the two nodes.
