The People class holds an unsorted list of humans. Initially, this list is empty. Existing Human objects may be added to the list using an insert method. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for…
What is wrong with this code it creates a file Exercise17_1 but no input into the file? package randomintegers; import java.io.*;import java.util.*; public class RandomIntegers { public static void main(String[] args)throws Exception{ PrintWriter out = new PrintWriter(new FileOutputStream("Exercise17_1.txt",(true)); { for(int j=0;j<100; j++) out.print((int)(Math.random()*100000)+""); } }}
FilelO 01: Write a Message Write a FileI001 class with a method named writeMessage() to takes message as a String and a filename (as a String) (in that order). Have the method, write the message to the filename. Your code will either need to 1) catch all checked exceptions or 2) use the throws keyword. public class FileI001{ public void writeMessage( String message, String filename ){

4. naloga:1. Write a program in the Java programming language where two threads access thecommon object of the Print class.2. Class Print contains only one variable type String, whose value is assigned by theconstructor.3. Both threads access the object of the class Print and print in reverse order the valueof the variable type String, letter by letter, where each letter is printed with a hyphen(–).Example for FAMNIT: T–T–I–I–N–N–M–M–A–A–F–F
Task 2: Fault Intolerant When reviewing logfiles, we need to be aware of the first time an ERROR crops up in the log. This can help us see how and when things might have gone wrong. For this task we will find the first event/message of type ERROR and print it out. Instructions 1. Create a file called Fault Intolerant.java 2. As with Task 1, open the file for reading in a try-catch block. 3. Read through the file line by line 4. If the message/event type is ERROR, throw a new Exception with the line as the exception message. 5. Catch the thrown exception and print out the message to the user then exit the program immediately. 6. If no error message is found, exit the program without printing anything. Sample Input/Output Example 1: 1: 1631077133.1621487 ERROR Carrier signal lost. Example 2: Cannot find logfile! Exiting...

Use stacks to implement a postfix-to-infix translator. Until the user closes the programme, it should continually read a postfix expression and output the identical infix expression. If the postfix expression entered is incorrect, throw an exception.
Java Program ASAP Modify this program so it passes the test cases in Hypergrade. Also change the public class to FileSorting import java.io.*;import java.util.Scanner;public class ConvertText { public static void main(String[] args) throws Exception { Scanner sc = new Scanner(System.in); System.out.println("Please enter the file name or type QUIT to exit:"); while (true) { String input = sc.next(); if (input.equalsIgnoreCase("QUIT")) { break; // Exit the program } else { String filePath = new File("").getAbsolutePath() + "/" + input; File file = new File(filePath); if (file.exists() && !file.isDirectory()) { try (BufferedReader br = new BufferedReader(new FileReader(file))) { String st; StringBuilder formattedText = new StringBuilder(); while ((st = br.readLine()) != null)…
2. After calling the Top() function of Stack Class it throws an exception. What can be the possible reason to throw the exception?
Task 6 Given a list named my_list. my_list=[10,20,30,40,60,100,2,5] Write a python program that takes the position as an input from the user and prints the element of that position from the list. If the user's input position is not in the range, return an exception stating "Index out of range". Make sure your program always prints "Program ended" at the end, no matter what happens. Hint: Use finally block Example 1: Input: 1 Output: 20 Program ended Example 2: Input: 10 Output: Index out of range. Program ended
