Question

What is the result of the following:

String stringA = " Wild " ;
String stringB = " Irish ";
String stringC = " Rose ";
String result = stringA.trim() + stringB + stringC.trim();

Answer 1

The code combines three strings into one, removing leading and trailing spaces from 'stringA' and 'stringC' and keeping 'stringB' unchanged. The final result is 'Wild Irish Rose'.

Step-by-step explanation:

In this question, we are dealing with string manipulation in the Java programming language. We have three strings: stringA = "Wild" , stringB = "Irish" , and stringC = "Rose". The variables stringA and stringC have whitespace at the beginning and end, which can be removed using the trim() method.

The result of the expression stringA.trim() + stringB + stringC.trim() is "WildIrishRose". The trim() method removes the whitespace from stringA and stringC, while the + operator concatenates the three strings together, resulting in the final string value.

So, the result of the expression is "WildIrishRose".

The result of the code snippet provided will be a concatenated String where stringA = " Wild ", with leading and trailing spaces removed using the trim() method, and stringC = " Rose ", also with leading and trailing spaces trimmed, concatenated with stringB which remains unaltered. The trim() method is used to eliminate leading and trailing spaces in a String. The final result after concatenation will be "Wild Irish Rose".
