this is my code:

case 1:

if(a>'0' &&  a<='9')

break;

case 2:

if(a>='0' &&  a<='9')
bol=true;

break;	

}

return bol;	
}


static boolean friends(char x[], char y[])
{
	
int i,j;

 for(i=0;i<x.length;i++){
 	
 for(j=0;j<y.length;j++)
      if(x[i]==y[j])
      break;	
 
 if(j==y.length)break;
 	
 }
  
  return (i==x.length);
 
}

static boolean almostFriends(char x[], char y[])
{

int i;
boolean bol;


for(i=0;i<x.length-1;i++){

StringBuffer xcopy=new StringBuffer();
xcopy.append(x);

 	
xcopy.setCharAt(i,(char)(x[i]-(char)1));

if(evalRangos((char)(x[i]-(char)1),1) && evalRangos((char)(x[i+1]+(char)1),2))
