When using the Java substring() method, a subset of the character sequence can be extracted from a string. The substring index must be any value from 0 to the length of a string. The java.lang.StringIndexOutOfBoundsException thrown by String methods to indicate that the beginIndex is negative , or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.


How to solve the StringIndexOutOfBoundsException:


  • Check the length of the string before using substring()
  • Exception handling using try...catch.
