I really would appreciate some help on this assignment. I need to make GUI boxes to display the system info such as on Microsoft Office. I have some code but not sure where to go with the rest of it. Help please. I will also include instructions that I was given.. I am working in JGrasp environment with Java.
In order to tuning programs to meet the hardware requirements and provide optimal performance, it is very important to retrieve system information for every program. In this assignment, you need to print out system information including:
a. Display mode
Width
Height
Bit depth
Refresh rate
b. OS information
Name
Version
Architecture
c. User information
Name
Country
Language
Home directory
Working directory
d. Java information
Java version
Installation path
Class path
Vendor
Vendor URL
e. Java Virtual Machine information
Total VM memory
Max VM memory
Free VM memory
f. CPU information
processor
vendor_id
model name
cpu MHZ
cache size
g. Physical memory information
MemTotal
MemFree
Buffers
Cached
To implement (a), you need to write codes like:
//The following codes are used to get display mode
GraphicsEnviron ment ge = GraphicsEnviron ment.getLocalGr aphicsEnvironme nt();
GraphicsDevice[] gs = ge.getScreenDev ices();
for (int j = 0; j < 1 /* gs.length */; j++) { //Only one display
DisplayMode dm = gs[j].getDisplayMode ();
int width = dm.getWidth();
int height = dm.getHeight();
int bitdepth = dm.getBitDepth( );
int refreshrate = dm.getRefreshRa te();
}
To implement (b) to (e), you need to write codes like:
//The following codes are used to get OS information
System.out.prin tln("Current OS Information");
System.out.prin tln("Name " + System.getPrope rty("os.name")) ;
System.out.prin tln("Version " + System.getPrope rty("os.version "));
System.out.prin tln("Architectu re " + System.getPrope rty("os.arch")) ;
//for others, you should check System.getPrope rty of JAVA.
To implement (f) and (g), you need to get information from two files (included in the assignment): \proc\cpuinfo and \proc\meminfo, and use StringTokenizer to retrieve required information from these two files.
It seems really simple but I feel I am just not knowledgeable enough to grasp it.
