In this tutorial, we will see simple program to find frequency of characters in a string in java. There are multiple ways to solve this proble. Let’s see one by one. Table of Contents [hide] Using counter array
String getToolName() Returns the name of this tool. void setFrequencyFields(Object frequencyFields) Sets the Frequency Field(s) parameter of this tool . void setInTable(Object inTable) Sets the Input Table parameter of this tool . void setOutTable(Object outTable) Sets the Output Table...
Scan the entire string and for each string element check the letter and increase the frequency in array by using ASCII value. (array[str[i]-'a']++)Like in str="aaabbccccddef",str [3] ='b'Thus, and str [2]-'a'=1Thus it increases the frequency of 'b' by 1 (array [str [3...
