A single single taxpayer with an income of $24,000 up to $58,150 (inclusive) falls into the 28% "tax bracket."
    // check that the income is within range for the 28% bracket
    if ( income >=24000 && income <= 58150  )
      System.out.println("In the 28% bracket." );
    else
      System.out.println("Time for an audit!" );
The AND combines the results of two relational expressions. This looks like:
income >= 24000 && income <= 58150 ------------- --------------- relational relational expression expression
Each relational expression must be complete. The following is a MISTAKE:
income >= 24000 && <= 58150 ------------- --------------- relational not a complete expression relational expression
In this INCORRECT logical expression, the characters that follow the &&
do not form a complete relational expression.
The Java compiler will complain if you wrote the program this way.
