The return type of the method is String, it represents string for the exception.

Example:

// of String toString() method of Throwable 

public class ToString {
    public static void main(String args[]) throws Exception {
        try {
            div(-3, 0);
        } catch (Exception ex) {
            System.out.println("ex.toString() :" + ex.toString());
        }
    }

    // This method divide number by 0
    public static void div(int d1, int d2) throws Exception {
        int res = d1 / d2;
        System.out.println("res :" + res);
    }
