I want to get the following output:
Hello Steve Andrews!
These are my variables:
a = "steve";
b = "Andrew"
I tried this:
System.out.print("Hello " + a + " " + b + "s");
I don't know where to put .toUpper() for steve. The s should be in uppercase. How do I do this?
Use StringUtils.capitalize(a),
"Hello " + StringUtils.capitalize(a) + " " + b + "s"
Capitalizes a String changing the first letter to title case as per Character.toTitleCase(char). No other letters are changed.
import org.apache.commons.lang.StringUtils
You could use StringUtils.capitalize(str), or if you want to do it by yourself:
public static String capitalize(String str) {
int strLen;
if (str == null || (strLen = str.length()) == 0) {
return str;
}
return new StringBuffer(strLen)
.append(Character.toTitleCase(str.charAt(0)))
.append(str.substring(1))
.toString();
}
You could also try using this method:
public static String capitalize(String str) {
str = (char) (str.charAt(0) - 32) + str.substring(1);
return str;
}
Though it should be noted that this method assumes that the first character in str is indeed a lowercase letter.
Charecter.toUpperCase this approach is rather misguided.
Character.toUpperCase doesn't do any such simple thing; it consults some internal lookup tables---it's a general mechanism that works the same way for all Unicode.Finally, I tried to do it without stringutils.. But anyways, thanks to all who helped :)
public class Hello
{
public static void main(String[] args){
String a = "steve";
String b = "Andrew";
String firstletter = a.substring(0,1);
String remainder = a.substring(1);
String capitalized = firstletter.toUpperCase() + remainder.toLowerCase();
System.out.print("Hello " + capitalized + " " + b + "s" );
}
}
