Final answer:
The error in the given statement is the use of the keyword 'String' while declaring the variable 'two words'.
To fix this error, you can use a valid data type such as 'String' or 'String[]' to declare the variable.
Corrected statement: String twoWords = "one two";
Step-by-step explanation:
A variable is a container that holds values that are used in a Java program. Every variable must be declared to use a data type.
The error in the given statement is the use of the keyword 'String' while declaring the variable 'two words'.
'String' is not a valid data type in many programming languages, including Java.
To fix this error, you can use a valid data type such as 'String' (with a lowercase 's') or 'String[]' (array of strings) to declare the variable.
Thus, the corrected statement: String twoWords = "one two";
