String length Implementation
String Length : 21


  • For string length implementation we have used char array to store the string as an array of character and by using while loop iterate for all character in the char array.
  • In each iteration length field will be incremented by one.
  • If string is null it will return value as zero at the initial step.
  • Java built in function to find the length of the string is length(). eg : str.length()
