Explanation & Answer
Buffered Reader is a class which uses an InputStream Reader object to read characters from a stream. If using System.in in the Inputstream Reader class, we can read the typed characters.
We can use the read() or readLine() functions to read data. read() will read a character and readLine() will read a whole line of characters(till you press enter). Also it throws an IOException which we must handle in our program
We also need to import java.io as it contains the necessary classes.
An example program
import java.io.*; public static void main (String[] args) throws IOException // throwing the IO exception which the buffered reader may generate { BufferedReader br =new BufferedReader(newInputStreamReader(System.in)); int T=Integer.parseInt(br.readLine()); for(int i=0;i<T;i++){ String s= br.readLine(); //read a line as string int[] m=newint[2];//create a 2 member array m[0]=br.read();//read the first number m[1]=br.read(); //read the second number System.out.println(s); //print out the string System.out.println(m[0]); //print out the first number System.out.println(m[1]); } }
