Answer 1

Answer :-

class StudentDetails
{
public static void main(String s[])
{
Student students[] = new Student[5];
  
students[0] = new Student();
students[0].StudentID = 1001;
students[0].FirstName = "Rajesh";
students[0].LastName = "K";
students[0].GPA = '3.2';
  
students[1] = new Student();
students[0].StudentID = 1002;
students[0].FirstName = "Suresh";
students[0].LastName = "S";
students[0].GPA = '4.5';
  
students[2] = new Student();
students[0].StudentID = 1003;
students[0].FirstName = "Ramesh";
students[0].LastName = "k";
students[0].GPA = '4';
  
  
students[3] = new Student();
students[0].StudentID = 1004;
students[0].FirstName = "Kamlesh";
students[0].LastName = "j";
students[0].GPA = '3.5';
  
students[4] = new Student();
students[0].StudentID = 1005;
students[0].FirstName = "Vignesh";
students[0].LastName = "A";
students[0].GPA = '3';
  
  
for(int i = 0; i < students.length; i++)
{
System.out.println("StudentID"+ students[i].StudentID + "Student FirstName " + students[i].FirstName + "Student LastName " + students[i].LastName + students[i].GPA+"out of 5");
}
}

}

class Student
{
  
int StudentID;
String FirstName;
String LastName;
String address;
double GPA;
}
