Answer:
Perform data backup on the work computer
Explanation:
It is very important that at every point in time that a technician will perform a maintenance, repair, or troubleshooting. the data on the work computer should be backed up to avoid loss. This is done to avoid data loss resulting from failure from hardware or software, backup provides copy of critical data immediately the maintenance is done, therefore backup is very important before any troubleshooting is done.
Answer:
public static String repeat(String text, int repeatCount) {
if(repeatCount < 0) {
throw new IllegalArgumentException("repeat count should be either 0 or a positive value");
}
if(repeatCount == 0) {
return "";
} else {
return text + repeat(text, repeatCount-1);
}
}
Explanation:
Here repeatCount is an int value.
at first we will check if repeatCount is non negative number and if it is code will throw exception.
If the value is 0 then we will return ""
If the value is >0 then recursive function is called again untill the repeatCount value is 0.
