Answer
1value
Reason — In Java, an identifier (e.g., variable, method, or class name) must follow these rules:
- It cannot start with a digit (e.g.,
1valueis invalid because it starts with1). - It can start with a letter, an underscore (
_), or a dollar sign. - It can contain letters, digits, underscores (
_), and dollar signs after the first character.
As 1value starts with a digit, hence it is an invalid identifier.

Consider the array given below:
char ch[] = {'A','E','I','O', 'U'};Write the output of the following statements:
System.out.println(ch[0]*2);:- 65
- 130
- 'A'
- 0
The size of '\n' is:
- 2 bytes
- 4 bytes
- 8 bytes
- 16 bytes
What are the resulting data type of the following explicit conversions?
int i; float f; double d; short s; char c; byte b;
(a) (float) i/b + d;
(b) (int)f*d + c/s;
(c) (char)i + f - b*d;
(d) (double) (f/i)*c + s;
(e) (char) d + b/i - f*s;
