Answer 2:

public class Student {
	
	String name;
	int age;
	boolean isJunior;
	char gender;
	
	Student()
	{
		name = "Mohamed";
		age = 23;
		isJunior = false;
		gender = 'm';
	}
	Student(String nme, int n, boolean job, char gen) 
	{
		name = nme;
		age = n;
		isJunior = job;
		gender = gen;
	}
	
	public static void main(String[] args) {
		
		Student s1 = new Student();
		Student s2 = new Student("Ayşe", 15, true, 'f');
		
		System.out.println("Name S1 = " + s1.name);
		System.out.println("Age S1 = " + s1.age);
		System.out.println("isJunior S1 = " + s1.isJunior);
		System.out.println("Gender S1 = " + s1.gender);

		System.out.println("\n\nName S2 = " + s2.name);
		System.out.println("Age S2 = " + s2.age);
		System.out.println("isJunior S2 = " + s2.isJunior);
		System.out.println("Gender S2 = " + s2.gender);
	}
}
//OUTPUT:

Name S1 = Mohamed
Age S1 = 23
isJunior S1 = false
Gender S1 = m


Name S2 = Ayşe
Age S2 = 15
isJunior S2 = true
Gender S2 = f
