In electronic resistor is a device that resists the current flow. In the following picture you can see a generally used resistor.
The SI unit for measure resistance is Ω(Ohm). Many students and electronics beginners harder to remember the resistor color code.
If you have a basic java knowledge for making a class and compile it, you can create a your own java program to calculate resistor value form it's color code!
here is the ResistorColorCode.java
import java.util.Scanner;
public class ResistorColorCode {
private String colorCodes;
private String[]numberCodes={"BLACK","BROWN","RED","ORANGE","YELLOW","GREEN","BLUE","PINK","GRAY","WHITE"};
private void inputColorCode(){
System.out.print("Enter color code(red-red-green):");
Scanner s=new Scanner(System.in);
colorCodes=s.nextLine().toUpperCase();
}
private String convertToValues(){
String result="";
int tmp=0;
String Codes[]=colorCodes.split("-");
System.out.println(Codes[0]);
result=""+getIndexOfCodeArray(Codes[0])+getIndexOfCodeArray(Codes[1]);
System.out.println(result);
tmp=getIndexOfCodeArray(Codes[2]);
double value=Long.parseLong(result)*Math.pow(10, tmp);
result=Double.toString(value);
return result;
}
private int getIndexOfCodeArray(String color){
int res=-1;
for(int i=0;i<numberCodes.length;i++){
if(numberCodes[i].equals(color))return i;
}
return res;
}
public static void main(String[] args) {
ResistorColorCode rcc=new ResistorColorCode();
while(true){
try {
System.out.println("©Sun Software Solutions");
rcc.inputColorCode();
System.out.println(rcc.convertToValues()+" Ohm(s)");
} catch (Exception e) {
e.printStackTrace();
System.err.println("Error input! Try again.");
}
}
}
}
