java - How to set the Text in TextFields to the numbers of an Array -

i need set each textfield in jframe corresponding number in pre-generated array of numbers not know how.

this need like:

here actionlistener class working with:

public class randlistener implements actionlistener { private final jtextfield[] tf;  public randlistener(jtextfield[] tf) {     this.tf = tf; }  @override public void actionperformed(actionevent e)  {     int [] rarray = new int[10];     random rnum = new random();     for(int k = 0; k < rarray.length; k++)     {         rarray[k] = rnum.nextint(100);                  }      if(e.getactioncommand().equals("brand"))     {          for(int k = 0; k < tf.length; k++)         {             tf[k].settext(/*i need set text of textfields numbers in array*/);         }     }     if(e.getactioncommand().equals("bmaxmin"))     {         //i need find maximum , minimum of array here     } }     } 

read on how strings in java work. basically, if want turn number string:

    tf[k].settext(/*i need set text of textfields numbers in array*/); 

turns into:

    tf[k].settext("" + rarray[k]); 

i believe done automatically java; number boxing turns primitive type respective wrapper (int -> integer) , then tostring() called on integer object represents primitive type.

now, find minimum , maximum, you're going have think little bit. elementary problem companies give weed out bad candidates. figure out once on own , you'll never forget it. think of how human; take current biggest/smallest , compare whatever you're looking @ currently.
