Unreachable Code Error in Java
Unreachable code error occurs when the code can’t be compiled due to a variety of reasons, some of which include: infinite loop, return statement before the unreachable line of code.
Let us see an example −
Example
public class Demo{ public static void main(String args[]){ int val = 5; for (;;){ if (val == 5){ break; System.out.println("If the condition is not true, this line would be printed. "); } } } }
Output
/Demo.java:11: error: unreachable statement System.out.println("If the condition is not true, this line would be printed. "); ^ 1 error
A class named Demo contains the main function, and a value is defined, and this value is checked for and an empty ‘for’ loop is run. If the value is found, the control breaks out of the loop otherwise prints a message. Since it is an infinite loop, it gives an unreachable statement error.
