### Question:
BinaryTree { public synchronized int getValue() { return this.value; } BinaryTree(int value); synchronized int getValue(); synchronized BinaryTree getEqual(); synchronized void setEqual(BinaryTree equal); synchronized BinaryTree getNotEqual(); synchronized void setNotEqual(BinaryTree notEqual);  }### Answer:
@Test public void testGetValue() { BinaryTree instance = new BinaryTree(15); int expResult = 15; int result = instance.getValue(); assertEquals(expResult, result); }
