Java - insert unicode character to string
0 points
In this article, we would like to show you how to insert unicode character to string in Java.
There are three different ways how to do it:
- with escape character e.g.
\u03c0that is equal toπ, - by pasting character directly to string,
- by converting codes to a string.
Quick solution:
xxxxxxxxxx1
String text = "π or \u03c0"; // U+03C02
3
System.out.println(text); // π or πOutput:
xxxxxxxxxx1
π or π
Space is represented by 0x20 (in hex) or 32 (in dec). It is necessary to add 2 additional zeros before code (e.g. \u0020).
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) throws Exception {4
5
String text = "π and \u03c0 are\u0020equal"; // U+03C0 U+00206
7
System.out.println(text); // π and π are equal8
}9
}Output:
xxxxxxxxxx1
π and π are equalIn this section you can find some emojis that we pasted directly to the string and received e.g \uD83C\uDF4F for the 🍏 (green apple emoji).
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) throws Exception {4
5
String apple = "\uD83C\uDF4F";6
String banana = "\uD83C\uDF4C";7
String cherry = "\uD83C\uDF52";8
9
System.out.println(apple);10
System.out.println(banana);11
System.out.println(cherry);12
}13
}Output:
xxxxxxxxxx1
