{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in) ;
char arr[] = new char[10] ;
System.out.println("Enter 10 characters") ;
for(int i=0;i< 10;i++)
arr[i] = sc.nextLine().charAt(0) ;
caseCount obj = new caseCount() ;
obj.performTask(arr) ;
}
public void performTask(char arr[])
{
int uppercaseCount = 0 ;
int lowercaseCount = 0 ;
for(int j=0;j< arr.length;j++)
{
if(arr[j]>='A' && arr[j]<='Z')
uppercaseCount++ ;
else if(arr[j]>='a' && arr[j]<='z')
lowercaseCount++ ;
}
System.out.println("No of lowercase characters : "+lowercaseCount) ;
System.out.println("No of uppercase characters : "+uppercaseCount) ;
}
