.charAt()

Returns the character at the given index in the string.

Syntax

string.charAt(int index)
  • index (required): An integer value that represents the index of the character value you want to retrieve.

Example 1

Use .charAt() to print the first five characters of the string "Hello World":

class CharacterAt {
public static void main(String[] args) {
String greeting = "Hello World";
System.out.println(greeting.charAt(0));
System.out.println(greeting.charAt(1));
System.out.println(greeting.charAt(2));
System.out.println(greeting.charAt(3));
System.out.println(greeting.charAt(4));
}
}

The output would be:

H
e
l
l
o

Example 2

Use .charAt() in a for loop to print all the characters in the string "Hello World":

class PrintAllCharacters {
public static void main(String[] args) {
String greeting = "Hello World";
for (int i = 0; i < greeting.length(); i++) {
char ch = greeting.charAt(i);
System.out.println(ch);
}
}
}

The output would be:

H
e
l
l
o

W
o
r
l
d
