[Solved]Java Homework Exercises Question 1 Modify Code Count 0 5 Modify Code Count Even Numbers 0 Q37121244
Java Homework Exercises:
Question 1:
Can you modify the code to count up from 0 to 5?
Can you modify the code to count all even numbers from 0 to20?
public class Countdown {
public static void main(String[] args) {
System.out.println(“Countdown to Launch: “);
for(int i = 5; i>= 0; i–) {
System.out.print(i +” “);
}
System.out.println(“Blast Off!”);
}
}
=======================================================
Question 2:
Modify SquareRootWhile.java to use a while loop to repeatedlyprompt users to type a number until
they type a non-negative number, and then computes the squareroot.
Expected output:
Type a non-negative integer: -5
Invalid number, try again: -1
Invalid number, try again: 11
The square root of 11 is 3.166
import java.util.Scanner;
public class SquareRootWhile {
public static void main(String args[])
{
System.out.print(“Type a non-negativeinteger: “);
Scanner console = newScanner(System.in);
int number = console.nextInt();
}
}
===========================================================
Question 3:
The program is used to count the number of occurrences of thechar ‘w’ in the string.
– Modify the program to …
• Resolve the syntax error
• Print the count of char ‘w’
– Expected Output:
• Number of w : 3
public class CountChar {
public static void main(String[] args) {
String str =”www.oracle.com”;
int max =str.length();
int count = 0;
// if (str.charAt(i) != ‘w’)
// continue;
count++;
System.out.println(“Counting w : ” + count );
}
}
=========================================================
Question 4:
Use a while loop and break statement.
• Implement the following:
– Accept 10 numbers from the user.
– Compute the sum of the numbers entered.
– When 0 is entered, the program must exit and display the sumof the numbers.
import java.util.Scanner;
public class ComputeSum {
public static void main(String[] args) {
}
}
