Q143. Given the fragment: 

String[][] arra = new String[3][]; 

arra[0] = new String[]{"rose", "lily"}; 

arra[1] = new String[]{"apple", "berry","cherry","grapes"}; 

arra[0] = new String[]{"beans", "carrot","potato"}; 

// insert code fragment here 

Which code fragment when inserted at line '// insert code fragment here', enables the code to successfully change arra elements to uppercase? 

A. String[][] arra = new String[3][]; 

arra[0] = new String[]{"rose", "lily"}; 

arra[1] = new String[]{"apple", "berry","cherry","grapes"}; 

arra[0] = new String[]{"beans", "carrot","potato"}; 

for (int i = 0; i < arra.length; i++) { 

for (int j=0; j < arra[i].length; j++) { 

arra[i][j] = arra[i][j].toUpperCase(); 

B. for (int i = 0; i < 3; i++) { 

for (int j=0; j < 4; j++) { 

arra[i][j] = arra[i][j].toUpperCase(); 

C. for (String a[]:arra[][]) { 

for (String x:a[]) { 

D. toUpperCase(); 

E. for (int i:arra.length) { 

for (String x:arra) { 

arra[i].toUpperCase(); 

Answer:

Explanation: 

Incorrect: 

not A: arra.length is 3, but the subarrays have 2, 3 and 4 elements. Index will be out of 

bound. 

not B: The subarrys are of different lengths. Index will be out of bound. 

not D: Compile error.

What is the result? 

A. p1.Test.class 

0.0 

B. <the summary address refrenced by ref> 0.000000 

C. Null 

0.0

Q148. Given: 

public class TestLoop { 

public static void main(String[] args) { 

int array[] = {0, 1, 2, 3, 4}; 

int key = 3; 

for (int pos = 0; pos < array.length; ++pos) { 

if (array[pos] == key) { 

break; 

System.out.print("Found " + key + "at " + pos); 

What is the result? 

A. Found 3 at 2 

B. Found 3 at 3 

C. Compilation fails 

D. An exception is thrown at runtime 

Answer:

Explanation: The following line does not compile: System.out.print("Found " + key + "at " + pos); 

The variable pos is undefined at this line, as its scope is only valid in the for loop. Any variables created inside of a loop are LOCAL TO THE LOOP.
