Sun 310-035: Sun Certified Programmer for Java 2 Platform 1.4

#91. Given:

 1. abstract class AbstractIt { 
 2. abstract float getFloat(); 
 3. } 
 4. public class AbstractTest extends AbstractIt { 
 5. private float f1 = 1.0f; 
 6. private float getFloat() { return f1; } 
 7. }

What is the result?

#92. Which four can be thrown using the throw statement? (Choose four)

#93. What produces a compiler error?

#94. Given:

 11. for( int i = min; i <max; i++) { 
 12. System.out.println(i); 
 13. }

If min and max are arbitrary integers, what gives the same result?

#95. Given:

 11. double d = Math.random();

Which is true about d after line 11?

#96. Given:

 1. public class Alpha{ 
 2. private static Character() ids; 
 3. 
 4. public static void main( String[] args){ 
 4. ids = new Character[args.length]; 
 5. for (int i=0; i<ids.length; i++){ 
 6. ids[i] = new Character( args[i] ); 
 7. System.out.print( ids[i] ); 
 8. } 
 9. } 
 10. }

What is correct?

#97. Given:

 1. public class Alpha{ 
 2. public static void main( string[] args ){ 
 3. if ( args.length == 2 ) { 
 4. if ( args.[0].equalsIgnoreCase(“-b”) ) 
 5. System.out.println( new Boolean( args[1] )); 
 6. } 
 7. } 
 8. }

And the code is invoked by using the command:
java Alpha –b TRUE
What is the result?

#98. Given:

 11. int i = 0, j = 1; 
 12. if ((i++ == 1) && (j++ == 2)) { 
 13. i = 42; 
 14 } 
 15. System.out.println(“i = “ + i + “, j = “ + j);

What is the result?

#99. Given:

 1. public class X ( 
 2. private static int a; 
 3. public static void main(String [] args) { 
 4. modify(a); 
 5. System.out.println(a); 
 6. } 
 7. public static void modify(int a) { 
 8. a++; 
 9. } 
 10 }

What is the result?

#100. Given:

 1. public class Test { 
 2. public static void add3 (Integer i) { 
 3. int val = i.intValue(); 
 4. val += 3; 
 5. i = new Integer(val); 
 6. } 
 7. 
 8. public static void main(String args[]) { 
 9. Integer i = new Integer(0); 
 10. add3(i); 
 11. System.out.println(i.intValue()); 
 12 } 
 13 }

What is the result?

[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] ... [29]
