Final answer:
The Java code snippet uses the split() method to divide a string into an array of substrings, then prints each element separated by a space. Assuming the code is corrected to loop through the entire tokens array, it would output 'A B C D '.
Step-by-step explanation:
The code provided is a Java snippet that will split a given string into an array of substrings based on the delimiters provided in the split method argument. Specifically, the string "A,B;C;D" will be split into separate strings at each occurrence of a comma (,) or semicolon (;). However, the code seems to have an error due to a missing part in the for loop declaration. Assuming the code is corrected to include the length of the tokens array (i.e., i < tokens.length), the output displayed would be each token followed by a space:
A B C D
Finally, there is also a missing print in the System.out.print statement in the loop.
