A simpler splitting logic from name to first and last name

[avivmu]

The current code has the following method for splitting name to two:

public void setName(String wholeName) {

	String[] parts = wholeName.split(" ");
	this.firstName = parts[0];
	if (parts.length > 1) {
		this.lastName = StringUtils.arrayToDelimitedString(Arrays.copyOfRange(parts, 1, parts.length), " ");
	} else {
		this.lastName = "";
	}
}

IMHO, the same could be done without using arrays and 3rd party libraries:

public void setName(String wholeName) {
	final int i = wholeName.indexOf(" ");
	if (i > 0) {
		this.firstName = wholeName.substring(0, i);
		this.lastName = wholeName.substring(i + 1);
	} else {
		this.firstName = wholeName;
		this.lastName = "";
	}
}

Should I submit a PR for this?
