Presuming all required import statements are in place, which lines of the following code will cause a compilation error?

1: class A {
2:    void m1() {throw new ArithmeticException();}
3:    void m2() {throw new ClassCastException();}
4:    void m3() {throw new IllegalArgumentException();}
5:    void m4() {throw new IndexOutOfBoundsException();}
6:    void m5() {throw new NullPointerException();}
7:    void m6() {throw new SecurityException();}
8: }
All listed exceptions extend "RuntimeException" class, hence all of them are Unchecked Exceptions. They can be declared in the method signature (using throws) but this is not required for compilation.
