(stdIn here: http://introcs.cs.princeton.edu/java/stdlib/StdIn.java.html)

package music; import stdlib.StdAudio; public class Chord e public static void playChord (double duration, double. .. frequencies) final int sliceCount = (int) (StdAudio. SAMPLE RATE * duration); final double[l slices new double[sliceCount+1]: for (int i=0; i

Explanation / Answer

use inner class concept

make Chord as inner class to PlayMusic class and make it static. call method playChord with the help of class name Chord..

Program

package music;

import stdlib.StdIn;

import stdlib.StdAudio;

public class PlayMusic{ //outer class

public static class Chord{ //inner class
public static void playChord(double duration,double ... frequencies){
final int sliceCount=(int)(StdAudio.SAMPLE_RATE*duration);
final double[] slices= new double[sliceCount+1];
for(int i=0;i<=sliceCount;i++){
for(double frequency:frequencies){
slices[i]+=Math.sin(2*Math.PI*i*frequency/StdAudio.SAMPLE_RATE);
}
slices[i]/=frequencies.length;
}
StsAudio.play(slices);
}
}

public static void main(String []ar)

{

StdIn.fromFile("data\painochords.txt");

while(StdIn.hasNextLine())

{

Strign line = StdIn.readLine();

double duration =Double.parseDouble(line);

line=StdIn.readLine();

String [] values=line.split("\s");

double[] frequencies = new double[values.length];

for(int i=0;i<values.length;i++)

{

frequencies[i]=Double.parseDouble(values[i]);

}

}

Chord.playChord(duration,frequencies);

}
