URGENT - Format a double?

ok its 1:36AM and ive got to finish this last tiny thing.

So ive done the calculations, now the times are 9AM - 5PM where u enter an int in the apropreite time/day.

Clicking calculate will show the weekly average which is a double

When im finding the average of all the weekly averages put together it displays for example:

13.666666666666666

how do i format it to only show 13.6 ?

code:

Code :

---

// WEEK ROW 10 AVERAGE
	double totalJ = weekA + weekB + weekC + weekD + weekE + weekF + weekG + weekH + weekI;
	txtBox[69].setText(Double.toString(totalJ));
 
	// WEEK ROW 11 AVERAGE
 
	double doubleK = totalJ / 9;
	txtBox[76].setText(Double.toString(doubleK));

---

ok thanks

meh fixed it :D the fix for this was:

Code :

---

// WEEK ROW 11 AVERAGE
 
	double doubleK = totalJ / 9;
	 DecimalFormat decimalFormat = new DecimalFormat("#.##");
	txtBox[76].setText(decimalFormat.format(doubleK));
