EXPERTY DESIGNED 1Z0-808 PRACTICE TEST

Which of the following is a checked Exception?

Consider below code of Test.java file:

1. package com.sampleproject.oca; 

2.  

3. public class Test {

4.     public static void main(String[] args) {

5.         /*INSERT*/ x = 7, y = 200;

6.         System.out.println(String.valueOf(x + y).length());

7.     }

8. }

Which of the following options, if used to replace /*INSERT*/, will compile successfully and on execution will print 3 on to the console?

Select 3 options.

Consider below codes of 3 java files:

1. //Super.java

2. package com.sampleproject.oca;

3.  

4. public interface Super {

5.     String name = "SUPER"; //Line n1

6. }

1. //Sub.java

2. package com.sampleproject.oca;

3.  

4. public interface Sub extends Super { //Line n2

5.  

6. }

1. //Test.java

2. package com.sampleproject.oca;

3.  

4. public class Test {

5.     public static void main(String[] args) {

6.         Sub sub = null;

7.         System.out.println(sub.name); //Line n3

8.     }

9.

Which of the following statements is correct?

Consider below code: 

1. //Test.java

2. package com.udayan.oca;

3.  

4. import java.time.LocalDate;

5.  

6. public class Test {

7.      public static void main(String [] args) {

8.          LocalDate joiningDate = LocalDate.parse("2006-03-16");

9.          System.out.println(joiningDate.withDayOfYear(29));

10.      }

11. }

What will be the result of compiling and executing Test class?

Consider below code:

1. //Test.java

2. package com.udayan.oca;

3.  

4. public class Test {

5.     public static void main(String[] args) {

6.         StringBuilder sb = new StringBuilder(100);

7.         System.out.println(sb.length() + ":" + sb.toString().length());

8.     }

9. }
