Find Duplicate Words In A File Using Java
String Right pad a string. String Find duplicate characters.
Java67 How To Find Highest Repeating Word From A Text Fil Words Text Java Programming Tutorials
Use a map or set data structures for identifying the uniqueness of words in a sentence.
Find duplicate words in a file using java. String Left pad a string. If the word is present in the HashMap then increase the value against the word. Outer loop will select a word and Initialize variable count to 1.
In the below code javautilScanner class is used to read words or lines from a file and also used to read words from a line. String Reverse words. String Get first 4 characters.
Else if inputFileexists promptscan. While oneLinehasNext String word oneLinenext. Systemoutprintln entrygetKey entrygetValue.
Then use the javautilArrayssortmyArrayList. String Find duplicate words. Output.
Using Collectionsfrequency. Create PrintWriter object for outputtxt 2. Algorithm Define a string.
By using HashSet a general-purpose Set implementation we can find duplicates in O n time. String Leading whitespaces. We are passing s as regex to this function.
Once the traversal is complete print the HashMap. One 3 the 3 that 3 of 2 in 2 some 2 to 1 summary 1 but 1 have 1 common 1 least 1 simplest 1. If a match found then increment the count by 1 and.
The task is to find duplicate elements in a Regular Expression in Java. This cnt will count the number of character-duplication found in the given string. The frequency method of Collections class in Java counts the frequency of the specified element in the given list.
Means words will be separated by blank space. . If you know in Java the Set interface doesnt allow duplicates and its based upon hash table data structure so insertion takes O 1 time in the average case.
Split the given string and store the words into a String array. Split the string into an array of words using split function. If HashMap contains word then increment its value by 1 and If a word is not present put that word as key and value as 1.
File inputFile new Filename. If it is not in the HashMap then store the word as key and 1 as the initial value. The words or lines are stored as a key in the hashmap.
Two loops will be used to find duplicate words. String Remove whitespaces. String Check empty string.
Inside the main the String type variable name str is declared and initialized with string w3schools. If inputFileexists Scanner read new ScannerinputFile. Int count 0 maxCount 0.
Traversing the array check if the word is in the HashMap or not. While readhasNext String line readnextLine. Public static void main String args throws Exception.
String thisOne. Run a loop for each line of inputtxt 31 flag false 32 Open BufferedReader for outputtxt 33 Run a loop for each line of outputtxt - If line of outputtxt is equal to current line of inputtxt - flag true - break loop 4. Convert the string into lowercase to make the comparison insensitive.
String name scannext. Read the file in line by line using a BufferedReader object and the readLine method into an ArrayList. String Reverse recursively.
Then use a for loop to rip through the array checking that the last element does not equal the previous one and if so sending it to a file or stdout or whatever. Public class MostRepeatedWord. ArrayList words new ArrayList.
Open BufferedReader for inputtxt 3. Given an Expression which is represented by String. Scanner oneLine new Scanner line.
String line word. Finally hashmap contains unique words or lines. Finally iterate over HashMap keyset and check with each keys value if it is greater than 1 then it is a duplicate word.
Next an integer type variable cnt is declared and initialized with value 0. String Trailing whitespaces. Used containsKey method of HashMap to check whether the word present or not.
Duplicate words or lines are detected using HashMap. So we will then find out the elements that have frequency more than 1 which are the duplicate elements. Split the string into words.
