any commercial apllication students??

Who all are doing biology?

Write a program to assign a full path and file name as given below.Using library functions,extract and output the file path,file name and file extension.
Where am I wrong?

import java.util.*;
class Ex
{
     public static void main(String args[])
            {
                  Scanner in = new Scanner(System.in);
System.out.println("Enter file name");
String s = "C:\Users\admin\Pictures\flower.jpg";
int m = s.lastIndexOf('.');
System.out.println(" Extension="+(s.substring(m+1));
int j = s.lastIndexOf('\');
System.out.println("Output path ="+s.substring(0,j+1);
System.out.println("File name="+(s.substring(j+1,m));
      }
}

what is the use of math.rint() please give an example also

WAP to input a word and remove the consecutive repeated characters by replacing the sequence of repeated characters by its single occurance
Sample Input:Jaaaaaavvvvvvvvaaaaaaaaa
Sample Output:Java

Would this program be accepted?
import java.util.*;
public class Q8
{
    static void main()
    {
        Scanner ob=new Scanner(System.in);
        System.out.println("Input String:");
        String s=ob.nextLine();
        s=s+"*";
        int i;int j;
        for(i=0;i<s.length()-1;i++)
        {
            char ch=s.charAt(i);
            if(ch==s.charAt(i+1))
            continue;
            else
            System.out.print(s.charAt(i));
        }
    }
}

Write the output for the following:
String s="Today is Test" ;
System.out.println(s.indexOf('T'));
System.out.println(s.substring(0,7) + " " +"Holiday");


According to me, the answer should be:Today is Holiday.
But the marking scheme says that it is:Today i Holiday [OR] Today Holiday 

Pls explain which is correct, and WHY TF are two answers being accepted?

Can someone give me the order of logical, relational, and arithmetic operators?
