Which one of the following is a valid statement?
A. char[] c = new char();
B. char[] c = new char[5];
C. char[] c = new char(4);
D. char[] c = new char[];
Answer: Option B
Solution (By Examveda Team)
The syntax for declaring and creating an array variable in java is:
dataType[] arrayRefVar = new dataType[arraySize];
Thus, option (A) and option (C) is syntactically wrong as parentheses( ( ) ) is used instead of square brackets( [ ] ).
Option (D) is incorrect as the size of the array is missing.
