### Question:
MatchRatingApproachEncoder implements StringEncoder { int leftToRightThenRightToLeftProcessing(final String name1, final String name2) { final char[] name1Char = name1.toCharArray(); final char[] name2Char = name2.toCharArray(); final int name1Size = name1.length() - 1; final int name2Size = name2.length() - 1; String name1LtRStart = EMPTY; String name1LtREnd = EMPTY; String name2RtLStart = EMPTY; String name2RtLEnd = EMPTY; for (int i = 0; i < name1Char.length; i++) { if (i > name2Size) { break; } name1LtRStart = name1.substring(i, i + 1); name1LtREnd = name1.substring(name1Size - i, name1Size - i + 1); name2RtLStart = name2.substring(i, i + 1); name2RtLEnd = name2.substring(name2Size - i, name2Size - i + 1); if (name1LtRStart.equals(name2RtLStart)) { name1Char[i] = ' '; name2Char[i] = ' '; } if (name1LtREnd.equals(name2RtLEnd)) { name1Char[name1Size - i] = ' '; name2Char[name2Size - i] = ' '; } } final String strA = new String(name1Char).replaceAll("\\s+", EMPTY); final String strB = new String(name2Char).replaceAll("\\s+", EMPTY); if (strA.length() > strB.length()) { return Math.abs(SIX - strA.length()); } else { return Math.abs(SIX - strB.length()); } }  @Override final Object encode(final Object pObject); @Override final String encode(String name); boolean isEncodeEquals(String name1, String name2);  }### Answer:
@Test public final void testleftTorightThenRightToLeft_ALEXANDER_ALEXANDRA_Returns4() { assertEquals(4, this.getStringEncoder().leftToRightThenRightToLeftProcessing("ALEXANDER", "ALEXANDRA")); }
@Test public final void testleftTorightThenRightToLeft_EINSTEIN_MICHAELA_Returns0() { assertEquals(0, this.getStringEncoder().leftToRightThenRightToLeftProcessing("EINSTEIN", "MICHAELA")); }
