Chapter 1, Problem 3P
Explanation of Solution
Purpose of the given code:
The given code is to product the two numbers and displays the result.
Syntax error:
An error which is occurred on the source code of a program is referred as “syntax error”; because the computer programs are strictly follows the syntax rules, if the code fails to prove its language syntax format then the compiler will throws an error.
Error in the given code:
n1=keyboard.nextInt();
n2=keyboard.nextInt();
The variables “n1” and “n2” are not declared in the given statement. Hence, it throws the syntax error.
Corrected code:
//Import required package
import java.util...
