Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
Answer:
public class Main
{
// required method
public static void fizzBuzz(){
// looping through 1 to 100
for(int i = 1; i <= 100; i++){
//if number is evenly divisible by both 3 and 5
if(i%3 == 0 && i%5 == 0){
System.out.println("fiz buzz");
}
// if number is divisible by 3
else if (i%3 == 0){
System.out.println("fizz");
}
// if number is divisible by 5
else if (i%5 == 0){
System.out.println("buzz");
}
// if number is not divisible by both 3 and 5
else {
System.out.println(i);
}
}
}
// main method
public static void main(String[] args) {
//calling function
fizzBuzz();
}
}

COMPLETE QUESTION
I. public class Test {
public static void main(String[] args){
System.out.println("Welcome to Java!");
}
}
II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}
Answer:
Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I
Explanation:
When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.
