Simple hash code generator which allows hash codes for primitives and Java objects to be combined for a single object hash code with: new HashCode().hash(value1) .hash(value2) .hash(value3) .getHashCode(); This also supports hashing of arrays by recursively hashing all elements in the array. Thanks to Item 8 in Joshua Bloch's "Effective Java" for the hash code theory: public class HashCode { static final int DEFAULT_SEED = 23; static final int fODD_PRIME_NUMBER = 37; int hash; // ------------------------------------------------- Constructors /** * Constructor - creates a hash code object initialized with * the given seed value. */ public HashCode(int seed) { this.hash = seed; } /** * Constructor - creates a hash code object initialized with * a default seed value. */ public HashCode() { this(DEFAULT_SEED); } // ---------------------------------------------------- Accessors /** * Returns the hash code stored in the object */ public int getHashCode() { return this.hash; } public String toString() { return String.valueOf(this.hash); } // ----------------------------------------------- Implementation /** * Adds the given value to the stored hash. This is done by * multiplying the current hash by fODD_PRIME_NUMBER and then * adding the new value to it. */ private void add(int value){ this.hash = fODD_PRIME_NUMBER * this.hash + value; } //basic number types: public HashCode hash(int value) { add(value); return this; } public HashCode hash(long value) { add((int)( value ^ (value >>> 32) )); return this; } public HashCode hash(short value) { add((int)value); return this; } public HashCode hash(byte value) { add((int)value); return this; } public HashCode hash(float value ) { add(Float.floatToIntBits(value) ); return this; } public HashCode hash(double value) { return hash(Double.doubleToLongBits(value)); } //other primitives: public HashCode hash(boolean value) { add(value ? 1 : 0); return this; } public HashCode hash(char value) { add((int)value); return this; } //objects: /** * Hashes an object.
