NO.46 public class Two {
public static void main(String[] args) {
try {
doStuff();
system.out.println(“1”);
}
catch {
system.out.println(“2”);
}}
public static void do Stuff() {
if (Math.random() > 0.5) throw new RunTimeException(); doMoreStuff();
System.out.println(“3 “);
}
public static void doMoreStuff() {
System.out.println(“4”);
}
}
Which two are possible outputs?

4 3 1

1 2

A: Output is 2 if Math.random() is greater than 0.5.
B: If Math.random() returns a value less equal to 0.5, the code won’t throw an exception, it will continue with the doMore() method which will println “4” after which the program will continue with the doStuff() method and will println “3”, after that we will be back in main() and the program will print “1”.

NO.56 Given:

What is the result?

int main 1

Object main 1

String main 1

Compilation fails

An exception is thrown at runtime

All methods have the same name but different signature since the parameters are different. There is no problem with that.
JVM will call the method with signature “public static void main(String[] args)”

NO.57 Which of the following can fill in the blank in this code to make it compile?

abstract

public

default

It will not compile with any as interfaces cannot have non abstract methods.

It will compile without filling the blank.

From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can’t use abstract there. Options B and E are incorrect as we can’t have non abstract method interface if they are not default or static. https;//docs.oraclexom/javase/tutorial/java/Iandl/defaultmethods.html

Compilation fails in the Test class.

Both the Employee class and the test class fail to compile.

NO.60 Given the code fragment:

A:

B: Compilation fails only at line n1
C: Compilation fails only at line n2
D: Compilation fails at both line n1 and line n2
