Consider a half width string 'Hello'. What java library should I use to get its full width equivalent which is 'Hello'.
Any sample code is also appreciated.
Half and full width characters differ by 65248 . So all you need to do is simply add that number to each character.
Example with stream:
public static String toFullWidth(String halfWidth) {
return halfWidth.chars()
.map(c -> c + 65248)
.collect(
StringBuilder::new,
(builder, c) -> builder.append((char) c),
StringBuilder::append
)
.toString();
}
Example with loop:
public static String toFullWidthWithLoop(String halfWidth) {
StringBuilder builder = new StringBuilder();
for (char c : halfWidth.toCharArray()) {
builder.append((char) (c + 65248));
}
return builder.toString();
}
Try this :
String s = "Hello" ;
System.out.println(s.replaceAll(""," ")) ;
you will get H ello
