Java Error Identifier excepted occurred when the programmer do not specify
the data type of a variable inside the class definition
Understand with code
In this Tutorial we want to describe you a code
that help you in understanding the Java error identifier excepted. For this we
have a class name Identifier Excepted, Inside the main method we have an input stream
reader that is used to decode the byte code into a character stream.BufferReader
is used to return you an object that is used to read the text from the character
present in inputstreamreader.We declare a string number num1,num2 and int add
variable .The System.out.print ln is used to print the respective number and
read them by the readline method ( ) and store in a add variable by adding
the both integer by parsing the both integer number. The code show an Identifier
error as we have not specified the proper type of data type for private x
variable.
IdentifierExcepted.java
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class IdentifierExcepted {
private x;
public static void main(String args[]) throws Exception {
InputStreamReader inputStreamReader = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(inputStreamReader);
String num1;
String num2;
int add;
System.out.print("1st num : ");
num1 = br.readLine();
System.out.print("2nd num : ");
num2 = br.readLine();
add = Integer.parseInt(num1) + Integer.parseInt(num2);
System.out.println("Sum = " + add);
}}

To remove this error you have to give proper data type for variable x in private x; i.e you should give any data type here like private int x;
