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.
Answer:
customers = int(input("How many customers? "))

name = input("Name of Customer " + str(i+1) + " ")
print("Oranges are $1.40 each.")

print("Apples are $.75 each.")
apples = int(input("How many Apples? "))
bill = oranges * 1.4 + apples * 0.75
