How To Input Char In Java

In this article we will show you the solution of how to input char in java, it's not as easy to accept character input as opposed to string or numeric input in Java.

The Java Scanner class supports nextInt(), nextLong(), nextDouble(), and more functions.

Nevertheless, taking character input in Java is a little more challenging because nextChar is not supported.

If nextChar() isn't functioning and you need to accept char input in Java, here's how to do it correctly.

The Java Scanner class does not contain the conventional nextChar() function. The next would be the finest and most straightforward replacement for accepting char inputs in Java().

charAt(0). Combining the straightforward next() command with the charAt(0) instruction tells Java to store the next letter or string included in the command line. This input could be a character, string, or number.

The charAt command allows you to filter out undesirable types of data and only allow char data types as input.

Any data type can be converted to a char type since charAt only produces output in the shape of a char value.

The nextInt() method of the Java Scanner class reads integer values, the nextDouble() method reads double values, the nextLong() method reads long values, etc.

For read one character in Java, however, there isn't a nextChar() function in the Scanner class.

We shall learn how to accept character inputs in Java in this part. Java's next() and chatAt() methods from the Scanner and String classes respectively are used to read a character.

A method of the Java Scanner class is next(). The next whole token found by this scanner is found and returned.

Input that complies with the delimiter pattern comes before a complete token and comes after it. Even though a previous call to hasNext() returned true, it can still block as it waits for input to scan.

Step By Step Guide On How To Input Char In Java :-

import java.util.Scanner;
   public class TalkersCode{
       public static void main(String[] args) {
           Scanner input = new Scanner(;
           System.out.print("Input any character: ");
           char t =;
           System.out.println("The TalkersCode content of small char: " + t);
  1. The import function is first defined as java.util.Scanner.
  2. Next, we construct the TalkersCode class.
  3. After that, input was initialized using scanner input.
  4. Next, we initialize input by using ().
  5. To Accept Char Input, Use charAt(0)
  6. Then, we printed the contents of "t."

Conclusion :-

By using the next() method, you can inform Java that an input with an undefined data type is about to be accepted. This input can contain an infinite amount of characters.

However, you are simply taking one character for input and putting it in a variable by employing the char At instruction and supplying '0' as the index. A single character will be the input line's return value.

The compiler doesn't worry that only one character was initialized because we told it to accept any input that came after.

I hope this article on how to input char in java helps you and the steps and method mentioned above are easy to follow and implement.
