0 points
In this article, we would like to show you how to add character to string in Java.
Quick solution:
xxxxxxxxxx1
String text = "ABC";2
char character = 'x';3
String result = text + character;4
5
System.out.println(result); // ABCx
In this example, we add character at the end of the text String using + operator.
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABC";5
char character = 'x';6
String result = text + character;7
8
System.out.println(result); // ABCx9
}10
}Output:
xxxxxxxxxx1
ABCxIn this example, we present how to add a character in the middle of the text String using substring() method.
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABC";5
char character = 'x';6
String result = text.substring(0,1) + character + text.substring(1);7
8
System.out.println(result); // AxBC9
}10
}Output:
xxxxxxxxxx1
AxBCIn this exmaple, we create a StringBuilder object and add both the char and the String to it using append() method.
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABC";5
char character = 'x';6
7
// create StringBuilder object8
StringBuilder stringBuilder1 = new StringBuilder();9
10
// Add text and character to the StringBuilder object11
stringBuilder1.append(text).append(character);12
13
System.out.println(stringBuilder1); // ABCx14
}15
}Output:
xxxxxxxxxx1
AxBC
