Hash table design
WebHash Table is a data structure which stores data in an associative manner. In a hash table, data is stored in an array format, where each data value has its own unique index value. … WebDec 27, 2024 · Hash code is an Integer number (random or non-random). In Java, every object has its own hash code. We will use the hash code generated by JVM in our hash function and compress the hash code we modulo (%) the hash code by the size of the hash table. So modulo operator is a compressor in our implementation.
