arrays - Java-Write in file -

i want name, last name , spacial code user, , save in 1 array, after write file. code doesn't have compiler error doesn't work.

public class writefile {  public static void main(string[] args){      try {          string array[][] = new string[100][2];         (int = 0; < array.length; i++) {             randomaccessfile raf=new randomaccessfile("d://employee.txt","rw");             string inputname=joptionpane.showinputdialog("please insert first name");             array[i][0]=inputname;             string inputlname=joptionpane.showinputdialog("please insert last name");             array[i][1]=inputlname;             string inputmeliic=joptionpane.showinputdialog("please insert melii code");             array[i][2]=inputmeliic;              raf.writeutf(array[i][0]);             raf.writeutf(array[i][1]) ;             raf.writeutf(array[i][1]);          }      } catch (filenotfoundexception e) {         e.printstacktrace();  //to change body of catch statement use file | settings | file templates.     } catch (ioexception e) {         e.printstacktrace();  //to change body of catch statement use file | settings | file templates.     }   } 

ok can modified code:

public static void main(string[] args){             randomaccessfile raf = null;     try {          string array[][] = new string[2][3];         raf=new randomaccessfile("d:\\employee.txt","rw");         (int = 0; < array.length; i++) {             string inputname=joptionpane.showinputdialog("please insert first name");             array[i][0]=inputname;             string inputlname=joptionpane.showinputdialog("please insert last name");             array[i][1]=inputlname;             string inputmeliic=joptionpane.showinputdialog("please insert melii code");             array[i][2]=inputmeliic;              raf.writechars(array[i][0]);             raf.writechar(':');             raf.writechars(array[i][1]) ;             raf.writechar(':');             raf.writechars(array[i][2]);             raf.writechars("\n");          }         raf.seek(0);          string str = raf.readline();         while(str != null ){             system.out.println(str);             string arr[] = str.split(":");             system.out.println(arrays.aslist(arr));             str = raf.readline();         }          raf.close();     } catch (filenotfoundexception e) {                 try {                     raf.close();                 } catch (ioexception ex) {                     logger.getlogger(ideone.class.getname()).log(level.severe, null, ex);                 }         e.printstacktrace();  //to change body of catch statement use file | settings | file templates.     } catch (ioexception e) {                 try {                     raf.close();                 } catch (ioexception ex) {                     logger.getlogger(ideone.class.getname()).log(level.severe, null, ex);                 }         e.printstacktrace();  //to change body of catch statement use file | settings | file templates.     }  }
