Problem with Conversion Program

Hey so im really new to java and I am having trouble with an assignment that converts meters to kilometers, inches, and feet based off of the users choice. Can anyone help with solving the errors::confused: Thanks

Here is what I got so far

import java.util.Scanner;

public class Program4RIT {

public static void main(String[] args){

double meters;

int decision;

meters = getInputLength();

}

public static int getInputLength(){

int meters;

Scanner keyboard = new Scanner (System.in);

System.out.println( "Enter a distance in meters" );

meters = keyboard.nextInt();

return meters;

}

{

System.out.println("1.Convert to kilometers");

System.out.println("2.Convert to inches");

System.out.println("3.Convert to feet");

System.out.println("4.Quit the program");

System.out.println("Enter your choice :");

Scanner input;

int decision = input.nextInt();

if (decision == 1){}

}

public static int getKilometers(){

double meters;

showKilometers1(meters);

}

private static void showKilometers1(double meters) {

// TODO Auto-generated method stub

}

{

int decision1;

if (decision1==2){}

}

public static int getInches(){

double meters;

showInches(meters);

}private static void showInches(double meters) {

// TODO Auto-generated method stub

}

{

if (decision1 == 3){

}

public static int showFeet(){

double meters;

showFeet(meters);

}

while (decision < 4);

if ( decision == 4)

{

System.out.println(" Bye!");

}

public static void showKilometers(double meters){

}

{

double kilometers;

int meters;

kilometers =( meters /1000);

System.out.println( meters + "The distance in meters is " + kilometers + " kilometers " );

}

public static void showInches(double meters);

{

double inches;

double meters;

inches=( meters *39.3700787);

System.out.println( meters + "The distance in meters is " + inches + " inches " );

}

public static void showFeet(double meters)

{

double feet;

feet =( meters *3.280839895);

System.out.println( meters + "The distance in meters is " + feet + " inches " );

}

{

}

{

}

}

}
