I keep getting this error and I do not know how to fix it. this is the code I've been working on:
please help me
import java.util.*;
public class TelephoneNumber {
public static void main(String[] args)
{String number;
int i=0,j=0;
char c;
Scanner in=new Scanner (System.in);
System.out.println("Enter the phone number: ");
number=in.nextLine();
number=number.toUpperCase();
c=number.charAt(i);
while(c!='\n'&&j<=7)
{switch(c)
{case 'A':
case 'B':
case 'C':
System.out.print("2");
j++;
break;
case 'D':

input code:

1 Import java.util. ; 2. public class Telephonel { 3 public static void main(String[] args) 4- { /*declare variables*/ String number; int i=0,j=0; char c; /*take input from users/ Scanner in=new Scanner (System.in); System.out.println("Enter the phone number: "); number-in.nextLine(); /*remove space from String / number - number.replaceAll("\\s", ""); number-number.toUpperCase(); C number.charAt(i); /*print the telephone number*/

while(c!='\n' && j<7) 19- /*check the Character and print*/ switch(c) case 'A': case 'B': case 'C': System.out.print("2"); j++; break; case 'D': case 'E': case 'F': System.out.print("3"); j++; break; case 'G': case 'H': case 'I': System.out.print("4"); j++; break; case 'J': case 'K': case'l': System.out.print("5"); j++; break; case 'M': case 'N: case '0': System.out.print("6"); j++; break; case 'P': case 'R': case's': System.out.print("7"); j++; break;

input code:

import java.util.*;
public class Telephone {
public static void main(String[] args)
{
/*declare variables*/
String number;
int i=0,j=0;
char c;
/*take input from user*/

System.out.println("Enter the phone number: ");
number=in.nextLine();
/*remove space from String*/
number = number.replaceAll("\\s", "");
number=number.toUpperCase();
c=number.charAt(i);
/*print the telephone number*/
while(c!='\n' && j<7)
{
/*check the Character and print*/
switch(c)
{
case 'A':
case 'B':
case 'C':
System.out.print("2");
j++;
break;
case 'D':

/*print -*/

System.out.print("-");
}
/*put condition so String array index don't go out the String*/
if(j!=6)
{
i++;
c=number.charAt(i);
}
}

}
}

explain:

char s /*take input from user*/ Scanner in=new Scanner (System.in); System.out.println("Enter the phone number: "); number-in.nextLine(); love space from String / number = number.replaceAll("\\s", ""); nulli: - umher.toUpperCase(). C=number.charAt(i); /*print the telephone number*/ while(c!='\n' && j<7) remove all the unneccary space from string so it is not disturb during counter in while loop. /*check the Character and print*/ switch(c) case 'A': case 'B': case 'C': System.out.print("2");

case 'T': case 'U': case 'V': System.out.print("8"); j++; break; case 'W': case 'X': case'Y': System.out.print("9"); j++; break; default: break; /*print - */ if(j==3) System.out.print("-"); /*put condition so String array index don't go out the String\/ if(j!=6) i++; C=number.charAt(i); put condition because for your last index array value go outside the range. به به
