Reading a paragraph from the command line on java console program -

the while loop in following program not terminate can't output in last line tries print variable paragraph console. there similar problems solutions not practicle , not them. please suggest solution.

import java.io.bufferedreader; import java.io.ioexception; import java.io.inputstreamreader;  public class test {       public static void main(string[] args) throws ioexception {         string line = "";         string paragraph = "";          system.out.println("enter text: ");         inputstreamreader isr = new inputstreamreader(system.in);         bufferedreader bufferedreader = new bufferedreader(isr);              while ((line = bufferedreader.readline()) != null)              {                   paragraph = paragraph + line + " ";              }           isr.close();           bufferedreader.close();           system.out.println(paragraph);     }//method main ends here  } 

the code

while ((line = bufferedreader.readline()) != null)

will never true if dont assign null line , , cant assign null object through console , means have code , enter key or other character end input.

like

while(!(line.equals("exit"))) {       //whatever } 

this means when type exit @ end , program terminate , print paragraph.

you can try snippet

import java.io.bufferedreader; import java.io.ioexception; import java.io.inputstreamreader;      public class test {           public static void main(string[] args) throws ioexception {             string line = "";             string paragraph = "";              system.out.println("enter text: ");             inputstreamreader isr = new inputstreamreader(system.in);             bufferedreader bufferedreader = new bufferedreader(isr);                                   {                      line = bufferedreader.readline();                       paragraph = paragraph + line + " ";                  }while(!line.equals("exit"));               isr.close();               bufferedreader.close();               system.out.println(paragraph);         }//method main ends here      }
