Question about loops

[BHCluster]

I have a class like this

Code:

public static double Euclidean(double[] array1, double[] array2)
{
	//Store the numbers of the both arrays
	double x1= array1[0];
	double y1=array2[0];
	double x2= array1[1];
        double y2= array2[1];
        double x3=array1[2];
        double y3=array2[2];

	//Compute the minus part of the formula
	double minusResult1 = y1-x1;
	double minusResult2 = y2-x2;
	double minusResult3 = y3-x3;

	//Square the answers
	double square1 = pow(minusResult1, 2);
 	double square2 = pow(minusResult2, 2);
        double square3 = pow(minusResult3, 2);

	//Sum the squares
	double sumOfSquares = square1+square2+square3;

	//Get the square root of the sumOfSquares
	double finalResult = sqrt(sumOfSquares);

	return finalResult;
}

In that class there is going to be 60 Y and 3 X and from which Result for all is going to be X-Y so in stead of writing the above lines 60 time i was wondering how this can be done ith a loop if it can be done.

Example:

Code:

          x1                x2                x3
y1    -9.30		5.65		-5.02
y2    -4.10		5.68		0.56
y3    4.75		0.11		2.86
y4    -1.54		-10.01		-1.99
y5    -6.29		5.62		-2.78
y6    -13.02		1.31		1.61
y7    -5.85		3.79		-6.56
y60  -12.71		-0.45		0.62

Any help is greatly appreciated.

You could put it into a for loop..

Code:

for(int i = 0; i < 60; i++){
		    	
}

[BHCluster]

you mean like this

Quote:

public static double Euclidean(double[] array1, double[] array2){

//Store the numbers of the both arrays
double x;
double y

String[] arrayX;
arrayX = new String[3];

// Read each line into the array
for (int i = 0; i < arrayX.length; i++){
arrayX[i] = x();
}

String[] arrayY;
arrayY = new String[60];

// Read each line into the array
for (int i = 0; i < myarrayY.length; i++){
arrayY[i] = y();
}

}

Yeah looks good to me. What happens when you compile it?

I know you get pm alot but I am bit desperate because I don't know how to convert this:

Code:

import java.io.*;
import static java.lang.Math.*;

class numbers
public static double Euclidean(double[] array1, double[] array2)
{
	//Store the numbers of the both arrays
	double x1= array1[0];
	double y1=array2[0];
	double x2= array1[1];
    double y2= array2[1];
    double x3=array1[2];
    double y3=array2[2];

	//Compute the minus part of the formula
	double minusResult1 = y1-x1;
	double minusResult2 = y2-x2;
	double minusResult3 = y3-x3;

	//Square the answers
	double square1 = pow(minusResult1, 2);
 	double square2 = pow(minusResult2, 2);
    double square3 = pow(minusResult3, 2);

	//Sum the squares
	double sumOfSquares = square1+square2+square3;

	//Get the square root of the sumOfSquares
	double finalResult = sqrt(sumOfSquares);

	return finalResult;
}

public static double Manhattan(double[] array1, double[] array2)
		{

//Store the numbers of the both arrays
double x1= array1[0];
	double y1=array2[0];
	double x2= array1[1];
    double y2= array2[1];
    double x3=array1[2];
    double y3=array2[2];

	//Compute the minus part of the formula
	double minusResult1 = y1-x1;
	double minusResult2 = y2-x2;
	double minusResult3 = y3-x3;
     //Square the answers
	double abs1 = abs(minusResult1 );
 	double abs2 = abs(minusResult2);
        double abs3 = abs(minusResult3 );

	//Sum the squares
	double sumOfAbs = abs1+abs2+abs3;

	//Get the square root of the sumOfAbs
	double finalResult = sqrt(sumOfAbs);

	return finalResult;
}

public static void main(String[] args)
	{


	double[] gene={-9.30, 5.65, -5.02};
	double[] gene1={-4.10, 5.68, 0.56};
	double EuclideanDist = Euclidean(gene, gene1);
	System.out.println("Euclidean distance = " + EuclideanDist);

	double ManhattanDist = Manhattan(gene, gene1);
	System.out.println("Manhattan = " + ManhattanDist);

	}

}

So it reads the file with 3 across and 60 down numbers. I have this code bellow which reads file and displays it on the screen but I cannot seem to get it to do what the code above does. If you know how to do it please help cos I don't know.

Code:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.io.Writer;
import static java.lang.Math.*;

public class csv {
public static double Euclidean(double[] array1, double[] array2){

//Store the numbers of the both arrays
	double x;
	double y

    String[] arrayX;
	arrayX = new String[3];

	// Read each line into the array
	for (int i = 0; i < arrayX.length; i++){
		arrayX[i] = x();
	}

	String[] arrayY;
	arrayY = new String[60];

	// Read each line into the array
	for (int i = 0; i < myarrayY.length; i++){
		arrayY[i] = y();
	}

	String[] MinusResults;
	MinusResults = new String[61];

	// Read each line into the array
	for (int i = 0; i < MinusResults.length; i++){
		MinusResults[i] = y() - x();
	}



}


public static double Manhattan(double[] array1, double[] array2){

}

public static void main(String[] args) throws Exception {


	// Set file name & path
	String filepath = "Data_Set_1.txt";
	//String output = "Output_Data_Set_1.txt";

	// Read in file
	FileInputStream in = new FileInputStream(filepath);
	BufferedReader br = new BufferedReader(new InputStreamReader(in));
	String strLine;

	//Write file
	//FileOutputStream out = new FileOutputStream(output);
	//BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(out));

	// Declare Array which will hold 61 lines
	String[] myarray;
	myarray = new String[61];

	// Read each line into the array
	for (int i = 0; i < myarray.length; i++){
		myarray[i] = br.readLine();
	}

	in.close();



	// Print out array info in desired order. Delete " characters
	for (int i = 1; i < myarray.length; i++){
		System.out.println(myarray[i].replace("\"", ""));

	}

  }
}

Any help is greatly appreciated. Thank you for taking interest.
