MurmurHash1のJava実装. オリジナル実装はunsigned intで行っているが、signed intでもビットパターンは変わらないので問題なし（のはず）
public class MurmurHash1 {
public long digest(byte[] data, int seed, boolean bigendian) {
int m = 0xc6a4a793;
int r = 16;
int len = data.length;
int h = seed ^ (len * m);

MurmurHash2のJava実装。32ビットハッシュを求めるやつと64ビットハッシュを求めるやつ
public class EncodeUtils {
public static long toLongBE(byte[] b, int offset) {
return (((long)b[offset+0] << 56) +
((long)(b[offset+1] & 255) << 48) +
((long)(b[offset+2] & 255) << 40) +
((long)(b[offset+3] & 255) << 32) +
((long)(b[offset+4] & 255) << 24) +
((b[offset+5] & 255) << 16) +

MurmurHash3のJava実装。32ビットと128ビットを求めるやつ。x86とx64で結果は異なる
public class EncodeUtils {
public static int toIntBE(byte[] b, int i) {
return ((b[i+0] << 24) + (b[i+1] << 16) + (b[i+2] << 8) + (b[i+3] << 0));
}
public static int toIntLE(byte[] b, int i) {
return ((b[i+3] << 24) + (b[i+2] << 16) + (b[i+1] << 8) + (b[i+0] << 0));
}

なんかWikiのドキュメントと構造が違うような。
