Question
Which one of the following is a valid statement? char[] c = new char();char[] c = new char[5]; char[] c = new char(4); char[] c = new char[];
Solution 1
The valid statement is: char[] c = new char[5];
This statement is creating a new character array in Java with a size of 5. The other statements are incorrect because:
- char[] c = new char(); is incorrect because you can't instantiate an array without specifying its size.
- char[] c = new char(4); is incorrect because array sizes should be specified with square brackets, not parentheses.
- char[] c = new char[]; is incorrect because you can't instantiate an array without specifying its size.
Solution 2
The valid statement among the given options is:
char[] c = new char[5];
This statement is creating a new character array 'c' with a size of 5 in Java. The other statements are not valid ways to declare and initialize an array in Java.
Solution 3
The valid statement is: char[] c = new char[5];
This statement is creating a new character array in Java with a size of 5. The other statements are not valid because:
- char[] c = new char(); is not valid because you cannot instantiate an array without specifying its size.
- char[] c = new char(4); is not valid because arrays in Java are not instantiated with parentheses, they use square brackets.
- char[] c = new char[]; is not valid because you cannot instantiate an array without specifying its size.
