Logical expression practice (Java)

/**
 * TesterBool
 * <br>
 *  <p>Build a logical expression using True(#) and False(#)
 *  method calls. Number the T/F calls sequentially, left to right.
 *  </p>
 *  <p>The output displays the numbers of the called methods, if
 *  evaluated, and the final result.
 *  </p>
 *  <p>Example: False(1) && (True(2) || False(3)) || True(4)
 *  </p>
 *  <p>Output:  1  4  --> true
 *  </p>
