https://blogs.oracle.com/geertjan/entry/support_for_custom_configuration_files

steps:
1. clean and build the project

2. package the project as Mac Os X Application.

3. copy the  project/build/launcher/etc/app.config file to a new file at project/nbproject/ and rename it as my.config.

4. Now, change/add the wanted arguments in a new my.config file.
for example,

add J-d64 -J-Xms512m -J-Xmx2G to the default_options in the new my.config file.

and save it.

5. Add app.conf=nbproject/my.conf to the project.properties file.

6. clean and build the project and package as Mac Os X Application, again.

7. check the project/build/launcher/etc/app.config file. It will have the default options overridden .

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 increase the size of heap memory for a Netbeans project

To increase the size of heap memory for a Netbeans project, do the following: 1. Change -Xms,  -Xmx, -XX:PermSize,to the desired memory size e.g :   -J-Xms512m -J-Xmx2G -J-XX:PermSize=2G -Xms defines the minimum size and Xmx the maximum.  These options are saved in the netbeans.conf file To find the file on a mac, go to Application/Netbeans/Netbeans7.3 right click and choose show Package Content and then go to: Contents/Resources/Netbeans/etc/netbeans.conf 2. Also add the same options in the Project Properties file of the Nebeans Project as well as in Netbeans Platform Config file. ( located in Important files folder of the project)   run.args.extra=-J-d64 -J-Xms512m -J-Xmx2G This file can found in the Important Files folder of the Netbeans project. This increases the memory for the Netbeans project also and not only for the Netbeans platform.
