Consider below code of Test.java file:
1. package com.sampleproject.oca;
2.
3. interface Perishable1 {
4. default int maxDays() {
5. return 1;
6. }
7. }
8.
9. interface Perishable2 extends Perishable1 {
10. default int maxDays() {
11. return 2;
12. }
13. }
14.
15. class Milk implements Perishable2, Perishable1 {}
16.
17. public class Test {
18. public static void main(String[] args) {
19. Perishable1 obj = new Milk();
20. System.out.println(obj.maxDays());
21. }
22. }
Which of the following statements is correct?
Given the code fragment:
Examine the content of App.java:
Which of the following is not a valid array declaration?
Given code:
package com.udayan.oca;
public class Test {
public static void main(String[] args) {
/*INSERT*/
arr[1] = 5;
arr[2] = 10;
System.out.println("[" + arr[1] + ", " + arr[2] + "]"); //Line n1
}
}
And below statements:
1. short arr [] = new short[2];
2. byte [] arr = new byte[10];
3. short [] arr; arr = new short[3];
4. short [2] arr;
5. short [3] arr;
6. int [] arr = new int[]{100, 100};
7. int [] arr = new int[]{0, 0, 0, 0};
8. short [] arr = {};
9. short [] arr = new short[2]{5, 10};
How many above statements can be used to replace /*INSERT*/, such that on execution, code will print [5, 10] on to the console?
