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
Answer:
The following code is:
do // set do while loop
{
response = stdin.next();
}
while (response != "Y" || response != "y" || response != "N" || response != "n");
// terminate do while loop
Explanation:
The following code starts with do while loop whose variables has already declared and then we assume the availability of the variable "stdin" which references the Scanner object and write some code to execute inside the do-while loop.
