The constructor for the class named MusicComposer10

The constructor for the class named MusicComposer10 is provided in Listing 8 . There is nothing new or unusual about this code so it shouldn't require further explanation.

Listing 8 . The constructor for the class named MusicComposer10.
public MusicComposer10(String[] args){//constructor//Save the args array. this.args = args;//Create default args data if no args data is provided on the command line.if(args.length == 0){ this.args = new String[3]; this.args[0]= "play";//Play the melody immediately this.args[1]= "6";//Pulses per minute this.args[2]= "TestData01.txt"; }//end if//Get a populated array containing audio data. AudioGraph01 audioGraph01 = new AudioGraph01(audioParams,this.args,melody);melody = audioGraph01.getMelody(); //Play or file the audio datanew AudioPlayOrFile01(audioParams,melody,this.args[0]).playOrFileData();}//end constructor //-------------------------------------------------------------------------//}//end class MusicComposer10.java

Listing 8 also signals the end of the class named MusicComposer10.

The class named AudioGraph01

A general purpose AudioGraph generator program

AudioGraph01 is a general purpose AudioGraph program that reads an input text file containing numeric values for y as a function of equally spaced values for xand produces an output melody that represents a graph of that data. The values for y are read as a comma-delimited list of values and are treated as type double . The name of the text file is input as a command-line parameter.

The input text file

The text file must be stored in a subfolder named Data that is a child of the folder containing the compiled program. The text file may be created manuallyusing a simple text editor or it may be created as the output of a program that evaluates a function.

Space characters are not allowed in the data.

are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
