### Question:
BinContent { public static long intToUnsignedLong(int value) { return value & 0x00000000ffffffffL; } private  BinContent(); static long intToUnsignedLong(int value); static int longToSignedInt(long value);  }### Answer:
@Test public void testIntToUnsignedLong() { int a = 0; int b = 1; int c = -1; int d = Integer.MAX_VALUE; int e = Integer.MIN_VALUE; int f = 12345; Assert.assertEquals("Wrong conversion", 0, BinContent.intToUnsignedLong(a)); Assert.assertEquals("Wrong conversion", 1, BinContent.intToUnsignedLong(b)); Assert.assertEquals("Wrong conversion", 4294967295L, BinContent.intToUnsignedLong(c)); Assert.assertEquals("Wrong conversion", Integer.MAX_VALUE, BinContent.intToUnsignedLong(d)); Assert.assertEquals("Wrong conversion", ((long) Integer.MAX_VALUE) + 1, BinContent.intToUnsignedLong(e)); Assert.assertEquals("Wrong conversion", 12345, BinContent.intToUnsignedLong(f)); }
