(java)

a. The following code has compilation AND logic errors. Rewrite the code (using the while loop) so it will compile correctly and print all the even numbers from 0 to 10 on one line separated by a space:

int j = 0;

while j > 10 ;

j + 2;

System.println(j, “ “);

b.You want to print the values of integers a and b to an external file “test123.txt”, assigned to the PrintWriter variable output. Correct the following statements:

include java.io.*;

PrintWriter output = new (“test123”);

System.output.print(a, b);

close.output();

Homework Answers

Answer #1

a.

The correct source code to print the all even number from 0 to 10 is given below:

//variable declaration and initialization
int j = 0;

//while loop
while(j<=10)
{
//print the value of j on the computer screen
System.out.print(j+" ");
j = j+2;
}

OUTPUT:

0 2 4 6 8 10

b.

The correct source code is given below:

import java.io.*;

//open the file
PrintWriter output = new PrintWriter("test123.txt");

//write into the file
output.print(a);
output.print(b);

//close the file
output.close();

IN JAVA!! You may be working with a programming language that has arrays, but not nodes. In this case you will need to save your BST in a two dimensional array. In this lab you will write a program to create a BST modelled as a two-dimensional array. The output from your program will be a two-dimensional array.   THEN: practice creating another array-based BST using integers of your choice. Once you have figured out your algorithm you will be able...
