how to initialize a destructive variable?
<p>hi i just want to ask how to initialize a variable properly when you're gonna use it in a condition? here's the code i made so far..</p>

<pre><code>import java.io.*;

public class Bwiset{
    public static void main(String[]args){
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        int t=0;
        double v=0;


        String vt,tt;
        double tc;

try{

        System.out.print("==================================\nVehicle Type \tCharge per km \n Car \t\t Php0.50\n Light Truck \t Php0.75");
        System.out.print("\n Bus \t\t Php1.00");
        System.out.print("\n Heavy Truck \t Php1.25\n");
        System.out.print("==================================\n");
        System.out.print("Km Travelled \t Ticket Color\n");
        System.out.print("   15 \t \t Yellow\n");
        System.out.print("   25 \t \t Blue\n");
        System.out.print("   50 \t \t Red\n");
        System.out.print("   75 \t \t Orange\n");




        System.out.println("Welcome! Please enter your vehicle type: ");
        vt=br.readLine();
        System.out.println("Enter ticket type: ");
        tt=br.readLine();





        if (vt=="car"||vt=="Car"||vt=="CAR"||vt=="cAr"||vt=="caR"||vt=="CAr"||vt=="cAR"){
            v=0.50;
        }else if (vt=="light truck"||vt=="Light Truck"||vt=="LIGHT TRUCK"){
            v=0.75;
        }else if (vt=="bus"||vt=="Bus"||vt=="BUS"){
            v=1.00;
        }else if (vt=="heavy truck"||vt=="Heavy Truck"||vt=="HEAVY TRUCK"){
            v=1.25;
        }



        if (tt=="Yellow"||tt=="yellow"||tt=="YELLOW"){
            t=15;
        }else if (tt=="BLUE"||tt=="blue"||tt=="Blue"){
            t=25;
        }else if (tt=="red"||tt=="RED"||tt=="Red"){
            t=50;
        }else if (tt=="orange"||tt=="ORANGE"||tt=="Orange"){
            t=75;
        }




        tc=v*t;



        System.out.println("Vehicle Type: " + vt);
        System.out.println("Ticket Type:" + tt);
        System.out.println("Charge According to Vehicle: " + v);
        System.out.println("Kilometers traveled according to ticket: " + t);
        System.out.print("Total Toll Charge: " + tc);



}catch(IOException e){
}

    }
}
</code></pre>

<p>to make it short, the program runs but when you input a vehicle type and a ticket type, it still returns <strong>0</strong> which isn't supposed to happen-- because i used conditions that assigns a certain value for each vehicle type and ticket types (also shown in the table that comes with the program). i've tried to search for proper initializations related to this but i can't find anything and i get so confused. please help. sorry for bein such a noob </p>
