Frequency count of words in a given text.

Write a Java Program to make frequency count of words in a given text.

Program Code in JAVA:

import java.io.*;

import java.util.*;

class Freq

{

public static void main(String[] args) throws Exception

{

DataInputStream dis=new DataInputStream(System.in);

System.out.println("Enter a String :");

String s=dis.readLine();

StringTokenizer st=new StringTokenizer(s);

int count=1,i=0;

int size=st.countTokens();

String words[]=new String[size];

while(st.hasMoreTokens())

{

words[i]=st.nextToken();

i++;

}

for(i=0;i<size;i++)

{

count=1;

for(int j=i+1;j<size;j++)

{

if(words[i].equals(words[j]))

{

count++;

move(words,j,size);

size--;

j--;

}

}

System.out.println(words[i]+" occurs "+count+" no of times");

}

}

static void move(String a[],int i,int size)

{

while(i<size)

{

if(i==size-1)

a[i]=null;

else

a[i]=a[i+1];

i++;

}

}

}

Program Output:

c:\java>javac Freq.java

c:\java>java Freq

Enter a String :

jai bolo hanuman ki jai

jai occurs 2 no of times

bolo occurs 1 no of times

hanuman occurs 1 no of times

ki occurs 1 no of times
