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[];

To determine which of the given statements is valid for declaring and initializing a character array in Java, let's analyze each option:

1. char[] c = new char();: This is invalid because you cannot instantiate a char array without specifying its size.

2. char[] c = new char[5];: This is valid as it creates a char array of size 5.

3. char[] c = new char(4);: This is invalid because the syntax used for array initialization does not allow for the use of parentheses like this.

4. char[] c = new char[];: This is also invalid since it does not specify the size or components of the array.

Conclusion

The only valid statement among the options provided is:

char[] c = new char[5];
