aking the CREATE call in the main program receives as a parameter the Graph array created at point Define a SHOW procedure/function to print an adjacency matrix, in matrix form Make the SHOW call in the main program, it receives as a parameter the Graph array created in point 2 Define an ADJACENCY procedure/function that receives, apart from the array, two integer values and returns a true value if there is a 1 in those positions of the array and False otherwise. Make the ADYACENCY call in the main program. To do this, ask and validate (between 1 and V) two vertices of the graph. Indicate if these two vertices are adjacent in the graph. That is, if ADYACENCY returns 1, write “Adjacency”, if they are not, say “Not adjacency”. Remember that the user is going to give values between 1 and V and that the matrix has values from 0 to V-1 For the Input degree option, use the function/procedure to add columns and do it with each of the columns. Remember that the user will see vertices between 1 and V and that the matrix has values from 0 to V-1 For the Loops option you can use the same one as ADYACENCY but the same vertex is passed twice as a parameter. The output should be written as (x,x) as seen in the example. Do it with all the vertices. Remember that the user will see vertices between 1 and V and that the matrix has values from 0 to V-1 For the Output degree option, use the function/procedure that adds rows and do it with each of the rows. Remember that the user will see vertices between 1 and V and that the matrix has values from 0 to V-1 The MENU keeps repeating until the user presses 0 (exit)

Question

In Java language Declare a constant V with value 5 Declare a variable named Graph that is an integer matrix of VxV Define a MENU procedure with the following text GRAPH 1. Create Graph 2.ShowGraph 3. Adjacency between pair 4. Input degree 5.Output degree 6.Loops 0.Exit Validate MENU so that it receives only valid options (from 0 to 6), otherwise send an error message and repeat the reading Make the MENU call in the main program Define a CREATE procedure/function to fill an array with random values between 0 and 1. Where 0 represents no adjacency and 1 indicates there is. Making the CREATE call in the main program receives as a parameter the Graph array created at point Define a SHOW procedure/function to print an adjacency matrix, in matrix form Make the SHOW call in the main program, it receives as a parameter the Graph array created in point 2 Define an ADJACENCY procedure/function that receives, apart from the array, two integer values and returns a true value if there is a 1 in those positions of the array and False otherwise. Make the ADYACENCY call in the main program. To do this, ask and validate (between 1 and V) two vertices of the graph. Indicate if these two vertices are adjacent in the graph.
