Question

(a) What is run time error? Explain with an example.
(b) Write Java expression for the following Mathematical expression V = a cube + b cube / 3
​

Answer 1

Answer:-

Question 1.

The errors that occurs during the execution of a program(i.e, at runtime) is called runtime error.

Example:- Division by zero.

For example, consider this program

class x{

public static void main(int a, int b)

{

System.out.println(a/b);

}

}

Now, if the user enters a=5 and b=0 from command line then,

a/b=5/0 which is undefined. This results in runtime error.

Question 2.

Java expression for V=a³+b³/3 is,

double V=Math.pow(a, 3)+Math.pow(b,3)/3.0;

Answer 2

Answer:

a) The error occuring while the execution of the program is called the Runtime error.

Example:

int a=10, b=0, c=0;

c=a/b;

//Here u are dividing a by 0.

b) Java expression for :V = a cube + b cube / 3

double V=Math.pow(a, 3) + Math.pow(b,3) /3;
