Create a custom exception class in Java

Example



class MyException extends Exception
{
private int detail;
MyException(int a)
{
detail=a;
}
public String toString()
{
return "MyException["+detail+"]";
}
}
class A14


{
static void compute(int a)throws MyException
{
System.out.println("called compute("+a+")");
if(a>10)
throw new MyException(a);
System.out.println("normal exit");
}
public static void main(String args[])
{
try
{
compute(1);
compute(20);
}
catch(MyException e)
{
System.out.println("caught "+e);
}
}
}
