This is my first post so sorry for any misunderstandings you may have, I made this calculator in C++ and it worked wonderful so I decided to make it in java. When I run the program it gives me no errors but my if statements inside my while loop don't work
import java.util.Scanner;
public class ohmlaw
{
public static void main(String args[])
{
float current;
float resistance;
float voltage;
String calchoice = new String();
Scanner cc = new Scanner(System.in);
System.out.println("OHMCAL, OHM'S LAW CALCULATOR BY RASHAAD BRYAN");
System.out.println();
System.out.println();
System.out.println();
System.out.println("Instructions");
System.out.println("If you want to calculate the voltage type voltage");
System.out.println("If you want to calculate the current type current");
System.out.println("If you want to calculate the resistance type resistance");
System.out.println("If you want to stop the program type stop");
System.out.println();
System.out.println();
System.out.println();
System.out.print("Please enter calculation choice ");
calchoice = cc.nextLine();
System.out.println();
while (calchoice != "stop")
{
if (calchoice == "current")
{
System.out.print("Please enter voltage (V) ");
voltage = cc.nextFloat();
System.out.println();
System.out.print("Please enter resistance () ");
resistance = cc.nextFloat();
System.out.println();
current = voltage/resistance;
System.out.println("The current is = " + current + "A");
System.out.println();
}
if (calchoice == "voltage")
{
System.out.print("Please enter current (V) ");
current = cc.nextFloat();
System.out.println();
System.out.print("Please enter resistance () ");
resistance = cc.nextFloat();
System.out.println();
voltage = current * resistance;
System.out.println("The voltage is = " + voltage + "V");
System.out.println();
}
if (calchoice == "resistance")
{
System.out.print("Please enter Voltage (V) ");
voltage = cc.nextFloat();
System.out.println();
System.out.print("Please enter current (I) ");
current = cc.nextFloat();
System.out.println();
resistance = voltage/current;
System.out.println("The resistance is = " + resistance + "");
System.out.println();
}
System.out.print("Please enter calculation choice ");
calchoice = cc.nextLine();
System.out.println();
System.out.println();
}
System.out.println("Thank you for using OHMCAL, have a nice day :D");
System.out.println();
}
}
