    Multiplying Variables in java

    Hi friends
    I program in java and so I use the best IDE for it, that it I use Eclipse IDE but the problem is that I am having a error on my varaible declaration line after I type every third line. Please check, I have posted it below
    Code:
    import java.math.*;
    .
    .
    .
    .
    .
    double cnt, energycnt, transRange;
    energycnt = cnt * Math.pow(transRange,2);
    Any idea on this. Please.

    Hi
    Please check the following code, this may help you.
    Code:
    public class sennode {
    private int xcord;
    private int ycord;
    private double energyLevel;
    public sennode(int xInit, int yInit, double newEnergy){
    xcord = xInit;
    ycord = yInit;
    energyLevel = newEnergy;
    }
    
    double const = 0 ;
    double energycnt = 0;
    double transRange = 0;
    
    energycnt = const * Math.pow(transRange,2);

    Hi
    Thanks for your help and your code.
    I have read your code in details but unfortunately that is not the problem for sure. May be you can try something different. Thanks again.

    	/**
    	 * @param xInit the x-coordinate for node
    	 * @param yInit the y-coordinate for node
    	 * @param newEnergy the initial energy for node
    	 */
    	public  sensorNode(int xInit, int yInit, double newEnergy){
    		
    		xcord = xInit;
    		ycord = yInit;
    		energyLevel = newEnergy;
    	}
    
    	double const = 0 ;
    	double energycnt = 0;
    	double transRange = 0;
