Answer:
None of the mentioned options
Explanation:
- If we define a method in a derived class with same declaration type as that of base class then it is said to be overriding a function which behaves differently which will depend on the object which is calling the method.
- Option a,b and c are not any kind of methods we implement using coding.
- Option d is done when number or data types of parameters are different than the declaration of the base type.
Answer:
int a[10] = {10,20,30,40,50,60,70,80,90,100};
Explanation:
In the above statement, we declare the integer data type array variable that is 'a' then, pass its index value that is 10 which means it contains only 10 values and initialize the components of the array variable that is starting with 10 and end at 100 in the difference of 10. So, the following declaration is correct according to the statement.
Answer:
int age = 10;
switch (age){
case 0:
case 1:
System.out.println("ineligible");
break;
case 2:
System.out.println("toddler");
break;
case 3:
case 4:
case 5:
System.out.println("early childhood");
break;
case 6:
case 7:
System.out.println("young reader");
break;
case 8:
case 9:
case 10:
System.out.println("elementary");
break;
case 11:
case 12:
System.out.println("middle");
break;
case 13:
System.out.println("impossible");
break;
case 14:
case 15:
case 16:
System.out.println("high school");
break;
case 17:
case 18:
System.out.println("scholar");
break;
default:
System.out.println("ineligible");
}
Explanation:
In java and many other programming languages, a switch statement is a way of having multiple branching options in a program. This is usually considered a more efficient way than using multiple if....else if statements. and the expression variables could be byte, char int primitive data types. etc. every branch (option) in a switch statement is followed by the break statement to prevent the code from "falling through". In the question The variable age is declared as an int and initialized to 10. and tested against the conditions given in the question.
