Printing of large double values in JAVA with or without scientific notation

Option 1:  Double d= 0.0007 ; System.out.println(d ); System.out.println(double d) Prints a long and then terminate the line. This method behaves as though it invokes print(long) and then println() . print(double d)  Prints a double-precision floating-point number. The string produced by String.valueOf(double) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method. So System.out.println(double d) changes double value to String. So 0.0007 becomes 7.0E-4. Option 2: Double d= 0.000000007; System.out.println(BigDecimal.valueOf(d) ); If you use System.out.println( BigDecimal.valueOf(d)), Translates a double into a BigDecimal , using the double 's canonical string representation provided by the Double.toString(double) method.  So 0.0007 is printed as 0.00070 but if the double number value is large like,  d= 0.000000007 then its bec...

To Make Window groups for Non Sigleton Windows

To Make Window groups for Non Sigleton Windows, choose one window as the main window,,i.e., that is the second window can be opened and closed only when first one is present. For example, in my case I have two singleton windows ( as have been described in a different post How to make Singleton windows) or two TopComponents, AlignmentFilterOption and AlignmentView. Here, I have choosen AlignmentFilterOption a my main window. Now in the AlignmentFilterOption TopComponent, (main window) make following changes: 1. make a private TopComponent object and define it as AlignmentView in the constructor private TopComponent tc; tc = new AlignmentView(this.ado.getAlignment()); 2.  In componentOpened() function, add AlignmentView object, so that whenever AlignmentFilterOption window is opened, AlignmentView widnow also opens. @Override     public void componentOpened() {                 if (tc != ...
