    Default 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:
    // 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 the fix for this was:

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