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?
Consider below code:
1. package com.udayan.oca;
2.
3. public class Test {
4. public static void main(String[] args) {
5. StringBuilder sb = new StringBuilder();
6. try {
7. for(;;) {
8. sb.append("OCA");
9. }
10. } catch(Exception e) {
11. System.out.println("Exception!!!");
12. }
13. System.out.println("Main ends!!!");
14. }
15. }
What will be the result of compiling and executing Test class?
Consider below codes of 3 java files:
1. //M.java
2. package com.sampleproject.oca;
3.
4. public class M {
5. public void printName() {
6. System.out.println("M");
7. }
8. }
1. //N.java
2. package com.sampleproject.oca;
3.
4. public class N extends M {
5. public void printName() {
6. System.out.println("N");
7. }
8. }
1. //Test.java
2. package com.sampleproject.oca.test;
3.
4. import com.sampleproject.oca.*;
5.
6. public class Test {
7. public static void main(String[] args) {
8. M obj1 = new M();
9. N obj2 = (N)obj1;
10. obj2.printName();
11. }
12. }
What will be the result of compiling and executing Test class?
