I want to convert any string to modified Camel case or Title case using some predefined libraries than writing my own functions.
For example "HI tHiS is SomE Statement" to "Hi This Is Some Statement"
Regex or any standard library will help me.
I found certain library functions in eclipse like STRING.toCamelCase(); is there any such thing existing?
This question is related to
java
regex
string
function
camelcasing
You can easily write the method to do that :
public static String toCamelCase(final String init) {
if (init == null)
return null;
final StringBuilder ret = new StringBuilder(init.length());
for (final String word : init.split(" ")) {
if (!word.isEmpty()) {
ret.append(Character.toUpperCase(word.charAt(0)));
ret.append(word.substring(1).toLowerCase());
}
if (!(ret.length() == init.length()))
ret.append(" ");
}
return ret.toString();
}
From commons-lang3
org.apache.commons.lang3.text.WordUtils.capitalizeFully(String str)
static String toCamelCase(String s){
String[] parts = s.split(" ");
String camelCaseString = "";
for (String part : parts){
if(part!=null && part.trim().length()>0)
camelCaseString = camelCaseString + toProperCase(part);
else
camelCaseString=camelCaseString+part+" ";
}
return camelCaseString;
}
static String toProperCase(String s) {
String temp=s.trim();
String spaces="";
if(temp.length()!=s.length())
{
int startCharIndex=s.charAt(temp.indexOf(0));
spaces=s.substring(0,startCharIndex);
}
temp=temp.substring(0, 1).toUpperCase() +
spaces+temp.substring(1).toLowerCase()+" ";
return temp;
}
public static void main(String[] args) {
String string="HI tHiS is SomE Statement";
System.out.println(toCamelCase(string));
}
