### Question:
Hashing { public String computeFullHash(String expression) { return DigestUtils.sha256Hex(expression); }  String computeHashPrefix(String expression, int significantBytes); String computeFullHash(String expression); static final int MIN_SIGNIFICANT_BYTES; static final int MAX_SIGNIFICANT_BYTES; }### Answer:
@Test public void testComputeFullHash() { String fullHash = hashing.computeFullHash("abcdefg"); Assert.assertEquals("7d1a54127b222502f5b79b5fb0803061152a44f92b37e23c6527baf665d4da9a", fullHash); }
