return str.substring(0, str.length() - 1);
Stringchop(String str)
chop 
return (str != null && str.length() > 0) ? str.substring(0, str.length() - 1) : str;
Stringchop(String str)
chop 
if (str == null) {
    return null;
int strLen = str.length();
if (strLen < 2) {
    return "";
int lastIdx = strLen - 1;
...
Stringchop(String str)

Remove the last character from a String. 

if (str == null) {
    return null;
int strLen = str.length();

return part;
...
Stringchop(String x)
chop 
if (x.length() == 0)
    return x;
return x.substring(0, x.length() - 1);
