Thread: Type mismatch: cannot convert from void to ClassX.MethodX

Trying to populate the Trans[] array with the methods in my transistor database (TransDBEE) and am getting the error as described in the title. Any suggestions would be much appreciated

Class 1
package TransistorBiasing;

import javax.swing.JList; //creates a list box for your JFrame
import TransistorBiasing.TransDBEE;

public class UseDB extends JFrame
{
private JList TransJList;

private final String TransNames[]={ "TIP120"};//an array of strings
private final TransDBEE Trans[]={TransDBEE.tip120()}; //HERE IS THE ISSUE LINE



public static void main( String args[])
{
}
}



Class 2
package TransistorBiasing;

class TransDBEE
{
public static int hfe;
public static int VBE;
public static int Icmax;

//static void tip120(int hfe, int Icmax, int VBE)
//static int tip120(hfe, Icmax, VBE)
static void tip120()
{
hfe=1000;
Icmax=5;
VBE=3;
}
}

Hello RevMoses77,
Your Trans[] array is of type TransDBEE so it should be assigned with a TransDBEE variable (for example an instance of the TransDBEE class). You tip120() method is void (returns nothing) that's why you get this error.
