1. 
   Ixtiyoriy dasturlash tilida Priority Queue strukturaga ega bo’lgan studentlar massivi ifodalovchi dastur tuzing. Ustuvorlikni student yoshi bo’yicha ifodalang.
   

Student Model:
package algorithm_design.labaratoriya.lab4;

public class Student {

private String firstName;
private String lastName;
private int course;
private int age;

public Student(String firstName, String lastName, int course, int age) { this.firstName = firstName;

this.lastName = lastName;
this.course = course;
this.age = age;
}

public String getFirstName() {

return firstName;
}

public void setFirstName(String firstName) {

this.firstName = firstName;
}

public String getLastName() {

return lastName;
}

public void setLastName(String lastName) {

this.lastName = lastName;
}

public int getCourse() {

return course;
}

public void setCourse(int course) {

this.course = course;
}

public int getAge() {

return age;
}

public void setAge(int age) {

this.age = age;
}
@Override
public String toString() {
return "Student{" +
"firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
", course=" + course +
", age=" + age +
'}';
}
}
Main:

package algorithm_design.labaratoriya.lab4;

import java.util.Comparator;
import java.util.PriorityQueue;
import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
PriorityQueue students = new
PriorityQueue<>(Comparator.comparingInt(Student::getAge));
int n = scanner.nextInt();
for (int i = 0; i < n; i++) {
System.out.print("Ism: ");
scanner = new Scanner(System.in);
String firstName = scanner.nextLine();
System.out.print("Familiyasi: ");
String lastName = scanner.nextLine();
scanner = new Scanner(System.in);
System.out.print("Kursi: ");
int course = scanner.nextInt();
System.out.print("Yoshi: ");
int age = scanner.nextInt();
Student student = new Student(firstName, lastName, course, age);
students.add(student);
System.out.println("----------------------");
}

System.out.println("Studentlar PriorityQueuega qo`shildi"); while (!students.isEmpty()) {

Student student = students.poll();

System.out.println(student.getFirstName() + " " + student.getLastName() + " - " + student.getAge());

}
}
}

Natija:
