Why a java program with multiple main methods is not giving any error?

Time:09-23

File Name = multiple_main_methods.java

class multiple_main_methods_two {
    public static void main(String[] args){
        System.out.println("Class second");
    }
}
class multiple_main_methods_one {
    public static void main(String[] args){
        System.out.println("Class first");
    }
}

Output

Class first

IDE used - IntelliJ IDEA

CodePudding user response:

IntelliJ is choosing a class to execute. Remember, you execute the main method in a class, not in a file.

Check it in your Run configurations enter image description here

CodePudding user response:

It is not giving error because your main methods belong to different classes i.e. multiple_main_methods_two and multiple_main_methods_one which is completely fine.
