In Java code, for a topological sort assignment:
How I load a .txt file and use its information to populate a
hashtable that maps IDs to characters, and add the IDs as nodes in
the graph.
Solution:-
/* I WRITE A CODE /*
public static void main(string[ ] args) throws I O Exception
{
String file Path= "test ,t x t";
hash Map<string ,String > map = new (Hash Map<String,String>( );
String line;
Buffered Reader reader = new Buffered Reader(new File Reader(file path));
while ((line = reader .read Line( ) ) !=NULL)
{
String[ ] parts = line .split(" : " ,2);
if ( parts. length >=2)
{
String Key = Parts[0];
String value = parts[1];
map.put(key , value);
} else{
System . out . print l n("ignoring line :" +line);
}
}
for( String Key :map .key Set ( ) )
{
System.out.print l n( key + ":" +map.get(key));
}
reader.close( );
}

JAVA - Natural Quick Sort .txt and Return ----------------------------------------------------------------------------- The program should input a .txt file like below and must use a Quick sort Algorithm ================ 6 10 4 19 10 12 8 6 0 1 2 3 ================ The first number "6" represents the index of the element to return after sort the second number on the top "10" represents the number of elements or size of array. The following numbers and lines are the elements that need to...
how do you load text from a txt file in java
Shortest Path (DAG) Students, In this coding assignment, you will be asked to write Java code to read a text file (input.txt) of a graph represented as an adjacency list. Example: A, 7, B, 9, C B, 1, C C, 8, E, 2, F D, 1, E, 3, G E, 3, G F, 3, D, -3, H H, 6, G K, 3, H, -1, F The graph represented by the adjacency list above looks like this: The graph is a...
using java create hash set that can for the file use a txt file: Hi my name is rick. (a) Read one word from the file. (b) Remove all non-alphanumeric characters from the word. A non-alphanumeric character is any character other than the lowercase and uppercase English letters, and the numerals 0 through 9. (c) Add the modified word to the hash set.
Using java: Store the files in .txt format and use the readByte() and writeByte() methods. File encryption is the science of writing the contents of a file in a secret code. Write an encryption program that works like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code....
Write a C++ program called ts.cpp that implements the topological sorting algorithm based on the DFS algorithm. Your program should read an input file name and determine if the input graph is a DAG (= directed acyclic graph) or not. If the graph is not a DAG, your program has to stop without further processing. However, if it’s a DAG, your program should display the starting node(s), popping-off order, and topologically sorted list. In the problem, you can assume that...
Help on writing a MATLAB code. Let's say i am given a .txt file and in that text file there are 26 rows that represent individual students grades and then 7 columns that represent specific homework assignments. We want to ask the user to select a specific homework assignment and output the mean and standard deviation for that assignment. Then we want to ask the user to select an individual student and output the mean and standard deviation for that...
Please provide C language code no c++ ,txt file also needed with comment Finish task 5 Task5: Breadth First Search (15 pts) · Write a program to read the graph information from the file and traverse the graph using BFS algorithm as introduced in lecture. The input for each algorithm is an undirected unweighted connected graph stored in a local file using an adjacency list. Following is the example of the input file (graph.txt) and the graph First line is...
