Cuestionario 17. 1Z0-808

Given:

public class MainMethod {
 
    void main() {
        System.out.println("one");
    }
 
    static void main(String args) {
        System.out.println("two");
    }
 
    public static void main(String[] args) {
        System.out.println("three");
    }
 
    void mina(Object[] args) {
        System.out.println("four");
    }
}

What is printed out when the program is executed?

public class ScopeTest {
 
    int j;
    int k;
 
    public static void main(String[] args) {
        new ScopeTest().doStuff();
    }
 
    void doStuff() {
        int x = 5;
        doStuff2();
        System.out.println("x");
    }
 
    void doStuff2() {
        int y = 7;
        System.out.println("y");
        for (int z = 0; z < 5; z++) {
            System.out.println("z");
            System.out.println("y");
        }
    }
}

Which two items are fields?

A method is declared to take three arguments. A program calls this method and passes only two arguments. What is the results?

Given the code fragment:

public class ForTest {
 
    public static void main(String[] args) {
        int[] array = {1, 2, 3};
        for (foo) {
        }
    }
}

Which three code fragments, when replaced individually for foo, enables the program to compile?

Given:

public class SampleClass {
 
    public static void main(String[] args) {
        AnotherSampleClass asc = new AnotherSampleClass();
        SampleClass sc = new SampleClass();
        sc = asc;
        System.out.println("sc: " + sc.getClass());
        System.out.println("asc: " + asc.getClass());
    }
}
 
class AnotherSampleClass extends SampleClass {
}

What is the result?

Given the code fragment:

int b = 3;
if (!(b > 3)) {
    System.out.println("square ");
}{
    System.out.println("circle ");
}
System.out.println("...");

What is the result?

What is the proper way to defined a method that take two int values and returns their sum as an int value?

Which two are Java Exception classes?
