java基礎--切割字符串

String originalStr = "originalStr";
String clipedStr = originalStr.substring(0, originalStr.length()-1);
Log.i(TAG, "onClick: originalStr = " + originalStr);
Log.i(TAG, "onClick: clipedStr = " + clipedStr);

: onClick: originalStr = originalStr
 onClick: clipedStr = originalSt

-----包左不包右。
