Show answer & explanation

Correct answer: D

In Java, the condition within a while loop must be a boolean expression. Line 6 uses an integer literal '1' as the condition, which causes a compilation error because integers cannot be implicitly converted to booleans. The class name 'While' is valid as Java keywords are case-sensitive, and the string concatenation syntax on line 8 is correct.
