I'm not a java programmer, I'm a VB programmer. I am doing this as part of an assignment, however, I'm not asking for help on something assignment related. I'd like to figure out how to get the OutputStreamWriter to work properly in this instance. I just want to capture the values I'm generating and place them into a text document. The file is generated, but only one entry exists, not the 40 I'm expecting. I could do this in a heartbeat with VB, but java feels very strange to me right now. Your help is appreciated.
Thanks,
Steve
Here's the code:
public static void main(String[] args){
long start, end;
double result,difference;
try {//OutputStream code assistance from http://tutorials.jenkov.com/java-io/outputstreamwriter.html
OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt");
Writer out = new OutputStreamWriter(outputStream);
for(int n=1; n<=20; n++){
//Calculate the Time for n^2.
start = System.nanoTime();
//Add code to call method to calculate n^2
result = mN2(n);
end = System.nanoTime();
difference = (end - start);
//Output results to a file
out.write("N^2 End time: " + end + " Difference: " + difference + "\n");
out.close();
}
} catch (IOException e){
}
try {
OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt");
Writer out = new OutputStreamWriter(outputStream);
for(int n=1; n<=20; n++){
//Calculate the Time for 2^n.
start = System.nanoTime();
//Add code to call method to calculate 2^n
result = m2N(n);
end = System.nanoTime();
difference = (end - start);
//Output results to a file
out.write("N^2 End time: " + end + " Difference: " + difference + "\n");
out.close();
}
} catch (IOException e){
}
}
//Calculate N^2
public static double mN2(double n)
{
n = n*n;
return n;
}
//Calculate 2N
public static double m2N (double n)
{
n = 2*n;
return n;
}
