java - Round Double value in Swing -

-

i have mentioned code given below.my question @ data.setvalueat(28.7567, 1, 1); value should displayed 28.757 taking 28.7567000000000 jtable.class adding zero's or other class there consider value double , how resove problem?

import java.awt.color; import javax.swing.imageicon; import javax.swing.jframe; import javax.swing.jscrollpane; import javax.swing.jtable; import util.leveleditor.components.letablemodel;  public class jrtest  {  public static void main(string args[]) {     object[][] datal = new object[30][30];     object[] titles = new object[30];       letablemodel model = new letablemodel(datal, titles);      jtable data = new jtable(model);      data.setfillsviewportheight(true);     data.setautoresizemode(jtable.auto_resize_off);     data.setshowgrid(true);     data.setgridcolor(color.black);     data.settableheader(null);      jframe frame = new jframe("test");      frame.add(new jscrollpane(data));      data.setvalueat(28.7567, 1, 1);      frame.pack();     frame.setvisible(true); } }

the first parameter of jtable.setvalueat() method object type. so, if want 28.757 pass directly string.

data.setvalueat("28.757", 1, 1);

or if want pass double value , if want should formatted 3 decimals, use formatter.

check following link: best way format double value 2 decimal places
