This answer is applicable to Linux.
There are several commands for copying files in Linux. cp and rsync are the most widely used. cp though, is the command used to copy files and their contents.
To copy a file named report1.txt to another file named report1uc.txt in the current directory, the following command is run.
 $ cp report1.txt report1uc.txt
You can change the case of the strings in the file by using the tr command.
 tr [:lower:] [:upper:]
For example,
 $ echo brainly | tr [:lower:]. [:upper:]
Result is BRAINLY.

Answer:
import java.util.Scanner;
public class ss11{
        public static void main (String[]args) {
              Scanner keyboard = new Scanner (System.in)
              String a1, a2, a3, a4, a5;
               int i1, i2, i3, i4, i5;
               System.out.println("Enter a four bit binary number:");
                a1= keyboard.next();
                a2= a1.substring(0,1);
                a3= a1.substring(1,2);
                a4= a1.substring(2,3);
                a5= a1.substring(3,4);
                 i1 = Integer.parseInt(a2);
                 i2 = Integer.parseInt(a3);
                 i3 = Integer.parseInt(a4);
                 i4 = Integer.parseInt(a5);
                 i1= i1 * 8;
                 i2= i1 * 4;
                 i3= i1 * 2;
                 i4= i1 * 1;
                 i5= i1+i2+i3+i4;
                 System.out.println("The converted decimal number is: +i5);
}
