Scanner class in Java supports nextInt(), nextLong(), nextDouble() etc. But there is no nextChar() (See this for examples) To read a char, we use next().charAt(0). next() function returns the next token/word in the input as a string and charAt(0) function returns the first character in that string, the number 0 in the function in CharAt(NUMBER) represents the index of the single word of the string taken input, and set that index character to the char variable.
Java
// Java program to read character using Scanner// classimport java.util.Scanner;public class ScannerDemo1 { public static void main(String [] args){ Scanner sc = new Scanner(System.in); char c = sc.next().charAt(1); // here this is the indexing of the element to take // System.out.println("c = "+c); } } |
Input :
ge
Output :
c = e
