Chapter 3b - Errors

Syntax error: Syntax errors are mistakes that a developer/user can do while writing the code. Examples of syntax errors are missing commas, quotes or spelling errors.

Example Syntax Error

System.out.print(" I Love Java ");// This line is correct
system.out.print(" I Love Java ");//Syntax Error as 's' of "system" is in lowercase.

Logical Error: A logical error is a bug in a program that causes it to produce wrong or unintended result. However, the program compiles and runs without showing an error on the console.

Example Logical Error

class Main {
public static void main(String args[]){
int a = 20;
int b = 0;
int result=a/b;// it is logical error as program will compile and throw
} // error at runtime i.e. java.lang.ArithmeticException: / by zero
