java

What lines will the compilation error occur in: class MyException1 extends Exception { } // 1 class MyException2 extends RuntimeException { } // 2 class A { void m1() { throw new MyException1(); } // 3 void m2() { throw new MyException2(); } // 4 }

java

What will be the result of the following program compilation and execution? public class Test { public static void main(String[] args) { int myInt = 0; float myFloat = 0; try { float result = myFloat / myFloat; } catch (RuntimeException re) { System.out.println("Exception 1"); } try { float result = myFloat / myInt; } catch (RuntimeException re) { System.out.println("Exception 2"); } try { float result = myInt / myFloat; } catch (RuntimeException re) { System.out.println("Exception 3"); } try { float result = myInt / myInt; } catch (RuntimeException re) { System.out.println("Exception 4"); } } }

java

Given the following code public class OverrideThrowsTest { public static void main(String[] args) // 1 { A a = new A(); a.method(); A ab = new B(); ab.method(); B b = new B(); b.method(); } } class A { public void method() throws IOException {} } class B extends A { public void method() throws FileNotFoundException {} } Select all the answers, for which, if placed into line 1, code will compile.
