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?
What will be the result of compiling and executing Test class?
1. //Test.java
2. package com.udayan.oca;
3.
4. import java.io.FileNotFoundException;
5.
6. public class Test {
7. public static void main(String[] args) {
8. try {
9. System.out.println(1);
10. } catch (NullPointerException ex) {
11. System.out.println("ONE");
12. } catch (FileNotFoundException ex) {
13. System.out.println("TWO");
14. }
15. System.out.println("THREE");
16. }
17. }
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?
What will be the result of compiling and executing Test class?

}

System.out.println("String");
}
static void m1(Object s) {
System.out.println("Object");
}
}
What will be the result of compiling and executing Test class?
package com.udayan.oca;

String str1 = " ";
boolean b1 = str1.isEmpty();
System.out.println(b1);
str1.trim();
b1 = str1.isEmpty();
System.out.println(b1);
}
}
