(Create a text file) Write a

Create a text file
Program Plan:
- Declare the class “writeText”.
- Definition for main class.
- Create an object to “PrintWriter” to create a new file named “Exercise17_01.txt”.
- For loop to iterate till 100.
- Write the 100 randomly generated integers to the file.
Program to create a file named “Exercise17_01.txt” to write 100 integers randomly to the created text file.
Explanation of Solution
Program:
//Import required packages
import java.io.*;
import java.util.*;
//Definition for class "writeText"
public class WriteText {
// Definition for main class
public static void main(String[] args) throws IOException {
// Try block
try (
/* Create an object for printWriter to write output to the text file */
PrintWriter out = new PrintWriter(new FileOutputStream(
"Exercise17_01.txt", true));)
{
// Loop to iterate
for (int j = 0; j < 100; j++)
// Generate the random number
out.print((int) (Math.random() * 100000) + " ");
}
}
}

- (团) (四) The Dog class has a constructor that takes two parameters. The first parameter is a String representing a dog's name and the second parameter is an int representing the dog's age, in months. 9 Mark for Review ARC The following code segment appears in a class other than Dog. Which of the following best describes the contents of dog1 and dog2 as a result of executing this code segment? Dog dogl new Dog ("Rex", 4); Dog dog2 dogl dog1; new Dog("Fido", 60); dog1 and dog2 are Dog variables that each contain the same Dog object, which represents a dog named "Fido' that is 60 months old. dogl is a Dog variable that contains a Dog object representing a dog named "Fido" that is 60 months old, and dog2 is a Dog variable that contains a Dog object representing a dog named "Rex" that is 4 months old. dogl and dog2 are Dog reference variables that each contain a reference to the same memory address that contains the Dog object representing a dog named "Fido' that is 60 months old. dogl is a…arrow_forwardThe following code segment is intended to assign to newword the result created by removing the first occurrence of "a" from word. Assume that the String variable word has been properly declared and initialized. This code segment works for some, but not all, values of word. int aLoc word.indexOf("a"); String newword word.substring(0, aLoc) + word.substring(aLoc + 1); 18 Mark for Review Which of the following conditions best describes the condition in which this code segment will not work a intended and will result in a runtime error? is the first character in word. is the last character in word. word does not contain the character "a". word contains only a sequence of multiple "a" characters.arrow_forwardConsider the following code segment, which is intended to create a String that consists of the last character in word and assign it to the variable lastChar String word / initialization not shown */; // line 1 int len word.length(); // line 2 String lastChar word.substring(len); // line 3 17 Mark for Review Which of the following best describes why this code segment will not work as intended? substring needs to be called with two parameters, so the method call in line 3 should be changed to word.substring(len, len + 1). len is not the correct index of the last character in word, so the method call in line 3 should be changed to word.substring(len - 1). len is not the correct index of the last character in word, so the method call in line 3 should be changed to word.substring(len + 1). substring cannot be called with a variable as the parameter, so the method call in line 3 should be changed to word.substring (word.length()).
