readLine() Function

ReadLine() function is used to take the input from user in string format.

The readLine method of class Datainputstream allows us to read a string data from keyboard.

When you are using BufferedReader & accepting the value or any line from the keyboard then all are store in a buffer memory where the buffer read that line using the ReadLine() method. if you are not using the BufferedReader then only using system.ReaLine() method then this ReadLine() method will read the character one by one using ReadLine() method.

ReadLine() method is use to read the data line by line.

It will read the data from the keyboard but line by line not character by character.

Actually the readLine() method will reads the data through the bufferdReader object. It reads only one line of data through keyboard. We can't enter the multiple lines of data at runtime.

This is the main functionality of the readLine() method.
