A StringIndexOutOfBoundsException is thrown when a String or StringBuffer object discovers an out-of-range index. The index is regarded as out of range if it is less than zero or more than or equal to the length of the string.
In Java, the substring() and charAt() methods throw the exception “String index out of range.” The “java.lang.” exception may be found here. StringIndexOutOfBoundsException: The string index is beyond the range: 0.” If both the begin and end index values are wrong, the exception “java.lang. The exception “StringIndexOutOfBoundsException: String index out of range” will be thrown. The StringIndexOutOfBoundsException is thrown when you try to substring or find a character in a java string.
