Method

Stringleft(String source, int length)
left 
if (source == null) {
    return null;
return ((length > source.length()) ? source : source.substring(0, length));
Stringleft(String source, String searchFor)
left 
String resultado = source;
int index = source.indexOf(searchFor);
if (index > 0)
    resultado = source.substring(0, index);
return resultado;
Stringleft(String source, String searchFor)
Returns the substring to the left of the specified substring in the specified String, starting from the left. 
int index = source.indexOf(searchFor);
if (index <= 0) {
    return "";
return source.substring(0, index);
Stringleft(String str, int count)
Returns the first n characters from this string, where n = count. 
if (str == null) {
    return null;
if (str.length() < count) {
    return str;
return str.substring(0, count);
Stringleft(String str, int len)
left 
return (str == null) ? null : ((len < 0) ? "" : ((str.length() <= len) ? str : str.substring(0, len)));
Stringleft(String str, int len)

Gets the leftmost len characters of a String.

If len characters are not available, or the String is null, the String will be returned without an exception. 

if (str == null) {
    return null;
if (len < 0) {
    return EMPTY;
if (str.length() <= len) {
    return str;
...
Stringleft(String str, int len)
Get substring from left 
if (!nullOrEmpty(str) && str.length() > len) {
    return str.substring(0, len);
return str;
Stringleft(String str, int len)
return str.substring(0,endIdx) * 
return str.substring(0, len);
Stringleft(String str, int len, String appendStrIfOver)
left 
if (str == null) {
    return null;
if (str.length() <= len) {
    return str;
if (appendStrIfOver == null || appendStrIfOver.isEmpty()) {
    return str.substring(0, len);
...
Stringleft(String str, int length)
left of string 
String rc = NVL(str);
if (rc.length() <= length) {
    return str;
return rc.substring(0, length);
