What is the output of the split() method when the limit is set to 0?

• The string is split into substrings, with trailing empty strings removed.
• The string is split into substrings, including trailing empty strings.
• The string is not split at all.
• The string is split into substrings, with the delimiter removed.

Answer explanation

The answer to this question is B. The split() method with a limit of 0 will split the string into as many substrings as possible, including trailing empty strings. This can be seen in the image, where the output of the split() method with a limit of 0 is bb and сс.

What is the delimiter used to split the string in the image?

• Comma (,)
• Period (.)
• Space ( )
• Tab (\t)

Answer explanation

The answer to the question is A. Comma (,). This is because the code in the image uses the split() method to split the string "JAVA, PHP, WORDPRESS, MYSQL, DATABASE" on the delimiter ,. The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array of strings will contain the following elements:

What is the first step in splitting a string by comma in Java?

• Create a string variable with comma separated string.
• Call the split() method on the string object.
• Convert the array to ArrayList of String.
• Print the array of strings.

Answer explanation

The answer to the question is A. Create a string variable with comma separated string. This is the first step in the process of splitting a string by comma in Java. The code in the image shows how to create a string variable called languages that contains the comma separated string "Java, JavaScript, C++, Python, Ruby, Scala". Once the string variable has been created, the next step is to call the split() method on the string object.

What is the value of the variable arr[3] in the image?

• This
• is
• a
• split

Answer explanation

The answer to the question is C. a. This is because the variable arr[3] contains the third element of the array arr, which is the string "a". The array arr is created by calling the split() method on the string "This-is-a-split-example--" with the delimiter -. The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array arr will contain the following elements:

What is the output of the code in the image?

• JAVA, PHP, WORDPRESS, MYSQL, DATABASE
• JAVA
• PHP
• WORDPRESS

Answer explanation

The answer to the question is A. JAVA, PHP, WORDPRESS, MYSQL, DATABASE. This is because the code in the image uses the split() method to split the string "JAVA, PHP, WORDPRESS, MYSQL, DATABASE" on the delimiter ,. The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array of strings will contain the following elements:

What is the output of the code in the image?

• String[3]{"Hello", "World", "2019"}
• String[2]{"Hello", "World 2019"}
• String[5]{"Hello", "World", "20", "1", "9"}
• String[4]{"Hello", "World", "201", "9"}

Answer explanation

The answer to the question is B. String[2]{"Hello", "World 2019"}. This is because the code in the image uses the split() method to split the string "Hello World 2019" on the delimiter . The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array of strings will contain the following elements:

What is the value of the variable subtitleArray at the end of the code in the image?

• String[23]{"w", "w", "w₁", "f", "a", "c", "e", "b", "o", "o", "k", ".", "f", "a", "c", "e", "b", "o", "o", "k", ".", "c", "o", "m", ".", "h", "e", "1", "1", "c"}
• String[22]{"w", "w", "w₁", "f", "a", "c", "e", "b", "o", "o", "k", ".", "f", "a", "c", "e", "b", "o", "o", "k", ".", "c", "o", "m"}
• String[21]{"w", "w", "w₁", "f", "a", "c", "e", "b", "o", "o", "k", ".", "f", "a", "c", "e", "b", "o", "o", "k"}
• String[20]{"w", "w", "w₁", "f", "a", "c", "e", "b", "o", "o", "k", ".", "f", "a", "c", "e", "b", "o", "o"}

Answer explanation

The answer to the question is A. String[23]{"w", "w", "w₁", "f", "a", "c", "e", "b", "o", "o", "k", ".", "f", "a", "c", "e", "b", "o", "o", "k", ".", "c", "o", "m", ".", "h", "e", "1", "1", "c"}. This is because the code in the image uses the split() method to split the string ".facebook.com/hello" on the delimiter ". The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array of strings will contain the following elements:

What is the length of the array s2 in the image?

• 17
• 18
• 19
• 20

Answer explanation

The answer to the question is B. 18. This is because the code in the image uses the split() method to split the string "{{ (( 4+ 5 )) }} on the delimiter "". The split() method returns an array of strings, where each element in the array is a substring of the original string that was split on the delimiter. In this case, the array s2 will contain the following elements:

What is the value of the variable name at the end of the code in the image?

• Andrew Carnegie
