Answer:
D. Identify the problem.
Explanation:
There are six steps or stages in computer system troubleshooting. They are,
1. Identify the problem: In the stage of troubleshooting, the user is interviewed to get a description of the problem. Reproducing the problem is essential to confirm the described problem of the system before moving to the next stage.
2. Establish a theory of probable cause: when the problem is identified, a list of the possible cause of the problem is made.
3. Test the theory to determine a cause: each items on the list of possible cause of the problem is tested to confirm its actual cause.
4. Resolve the problem.
5. Verify full system functionality
6. Document the findings, actions and outcomes.
Answer:
Here is the program for the given question
Explanation:
class StringSet
{
ArrayList<String> arraylist; //a reference variable of ArrayList of generic type String
//A no argument constructor.
public StringSet()
{
arraylist=new ArrayList<String>(); //instantiating the ArrayList object
}
//A mutator that adds a String newStr to the StringSet object.
void add(String newStr)
{
arraylist.add(newStr); // add(String) method to add string to the arraylist
}
//An accessor that returns the number of String objects that have been added to this StringSet object.
int size()
{
return arraylist.size(); // size() method which gives the number of elements in the list
}
//An accessor that returns the total number of characters in all of the Strings that have been added to this StringSet object.
int numChars()
{
int sum = 0;
for(String str:arraylist) //for-each loop; can be read as for each string in arraylist
{
sum+=str.length();
}
return sum;
}
//An accessor that returns the number of Strings in the StringSet object that have exactly len characters.
int countStrings(int len)
{
int count = 0;
for(String str:arraylist)
{
if(str.length() == len)
count++;
}
return count;
}
}
Yes because the main story is 1+1 so it would be
Answer:
True
