Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
Answer: A VLAN mismatch
Explanation:
The VLAN mismatch is the process when the both ends of the truck line are not connected correctly and properly between the two switches.
- The configuration of the VLAN is done correctly as it is important to connecting the VLAN on either of the ends for avoiding the VLAN mismatch occurrence.
- By default the truck allow the VLAN 2094 for traversing the trunk by using the native VLAN in the form of VLAN 1.
Therefore, VLAN mismatch is the correct answer.
Answer: Constructors can specify parameters but not return types.
Explanation:
public class Student {
int roll_no;
public Student(int a) {
roll_no = a;
}
public static void main(String[] args) {
Student abs = new Student(10);
System.out.println(abc.roll_no);
}
}
In the above code we have illustrated the working of constructors. We have a class with the name Student. then a constructor is created of the class called as the class constructor. In the main we create an object of the class and with this object we invoke the constructor and also pass a parameter. Here in the code we are passing the roll no of the student.
So we can say that constructor is called during the runtime when the object created invokes the constructor so a constructor can have many arguments but it does not have a return type.
