This small program includes an expression that intentionally causes a divide-by-zero error:
public class Main {
public static void main(String args[]) {
int d = 0;
int a = 42 / d;
}
}
Here is the exception generated when this example is executed:
java.lang.ArithmeticException: / by zero
at Main.main(Exc0.java:4)
Here is another version of the preceding program that introduces the same error but in a method separate from main( ):
public class Main {
static void subroutine() {
int d = 0;
int a = 10 / d;
}
public static void main(String args[]) {
subroutine();
}
}
The resulting stack trace from the default exception handler shows how the entire call stack is displayed:
java.lang.ArithmeticException: / by zero
at Main.subroutine(Exc1.java:4)
at Main.main(Exc1.java:7)
