Question

What you need to turn in: You will need to include an electronic copy of your report (standalone) and source code (zipped) of your programs. All programming files (source code) must be put in a zipped folder named "labl-name," where "name" is your last name. Submit the zipped folder on the assignment page in Canvas; submit the report separately (not inside the zipped folder) as a Microsoft Word or PDF file. O You should adhere to the following guidelines: . State whether your code works. . Clearly explain how to compile and execute your code. . If needed/applicable, report/analyze (as appropriate) the results. The quality of analysis and writing is critical to your grade. Good writing and presentation are expected.

write programs with detailed instructions on how to execute.

code is java

Answer 1

import java.util.Scanner;

public class HexadecimalToDecimal {

   public static void main(String[] args) {
       String ch;
       Scanner sc=new Scanner(System.in);
       System.out.println("Enter a character: ");
       ch=sc.next();
       try{
           System.out.println("The hex value of "+ch+" is : "+Integer.valueOf(ch, 16));
       }
       catch(Exception e){
           System.out.println("The character "+ch+" is invalid:"+ch+" is not a hexadecimal digit");
       }
       sc.close();
   }

}

Enter a character: The hex value of 4 is : 4

Enter a character: The hex value of B is : 11

Enter a character: The character I is invalid:I is not a hexadecimal digit

import java.util.Scanner;

public class DecimalToBinary {

   public static void main(String[] args) {
       Scanner sc=new Scanner(System.in);
       System.out.println("Enter decimal number: ");
       int decimal=sc.nextInt();
       System.out.println("The binary value of "+decimal+" is : "+convertToBinary(decimal));
   }
   public static String convertToBinary(int decimal){
       String binary="";
       StringBuilder sb=new StringBuilder();
       int temp=decimal;
       int mod=0;
       while(temp>0){//will divide 66 by 2 till the last dividend is less than 0
           mod=temp%2;//will get the quotient and add to string
           temp=temp/2;//will get the new dividend by dividing with 2
           binary=binary+mod;//adds the binary bits to string binary it will be 0100001
       }
       sb.append(binary);//adding to a string builder
       binary=sb.reverse().toString();//reverses the string builder to get exact output(1000010)
       return binary;
      
   }

}

Enter decimal number: The binary value of 66 is : 1000010
