Rewrite this if/else if code segment into a switch statement int num = 0; int a = 10, b = 20, c = 20, d = 30, x = 40; if (num &g
Tanya [424]

Answer:

public class SwitchCase {

   public static void main(String[] args) {

       int num = 0;

       int a = 10, b = 20, c = 20, d = 30, x = 40;

       switch (num){

           case 102: a += 1;

           case 103: a += 1;

           case 104: a += 1;

           case 105: a += 1;

           break;

           case 208: b += 1; x = 8;

           break;

           case 209: c = c * 3;

           case 210: c = c * 3;

           break;

           default: d += 1004;

       }

   }

}

Explanation:

  • Given above is the equivalent code using Switch case in Java
  • The switch case test multiple levels of conditions and can easily replace the uses of several if....elseif.....else statements.
  • When using a switch, each condition is treated as a separate case followed by a full colon and the the statement to execute if the case is true.
  • The default statement handles the final else when all the other coditions are false

State why hexadecimal is used to display the error code
maxonik [38]
“Hexadecimal uses digits that more closely resemble our usual base-10 counting system and it's therefore easier to decide at a glance how big a number like e7 is as opposed to 11100111. Higher information density. With 2 hexadecimal digits, we can express any number from 0 to 255.”
