Answer:
The output is: Your cost is 100
Explanation:
Given
The above code snippet
and
Required
Determine the output of the code
if cost < 70 or cost > 150
The above condition checks if cost is less than 70 or cost is greater than 150
This condition is false because 100 is neither less than 70 nor is it greater than 150
So, the else statement will be executed.
discount = cost
Which means
discount = 100
So, the print instruction will print: Your cost is 100

Explanation:
CODE:-
import java.util.*;
class UserName{
ArrayList<String> possibleNames;
UserName(String firstName, String lastName){
if(this.isValidName(firstName) && this.isValidName(lastName)){
possibleNames = new ArrayList<String>();
for(int i=1;i<firstName.length()+1;i++){
possibleNames.add(lastName+firstName.substring(0,i));
}
}else{
System.out.println("firstName and lastName must contain letters only.");
}
}
public boolean isUsed(String name, String[] arr){
for(int i=0;i<arr.length;i++){
if(name.equals(arr[i]))
return true;
}
return false;
}
public void setAvailableUserNames(String[] usedNames){
String[] names = new String[this.possibleNames.size()];
names = this.possibleNames.toArray(names);
for(int i=0;i<usedNames.length;i++){
if(isUsed(usedNames[i],names)){
int index = this.possibleNames.indexOf(usedNames[i]);
this.possibleNames.remove(index);
names = new String[this.possibleNames.size()];
names = this.possibleNames.toArray(names);
}
}
}
public boolean isValidName(String str){
if(str.length()==0) return false;
for(int i=0;i<str.length();i++){
if(str.charAt(i)<'a'||str.charAt(i)>'z' && (str.charAt(i)<'A' || str.charAt(i)>'Z'))
return false;
}
return true;
}
public static void main(String[] args) {
UserName person1 = new UserName("john","smith");
System.out.println(person1.possibleNames);
String[] used = {"harta","hartm","harty"};
UserName person2 = new UserName("mary","hart");
System.out.println("possibleNames before removing: "+person2.possibleNames);
person2.setAvailableUserNames(used);
System.out.println("possibleNames after removing: "+person2.possibleNames);
}
}
