Not so. Code readability is important but clarity != short.

Once again you are trying to use bitwise & for a logical statement. Please see Learning the Java Language > Language Basics > Operators. Logical AND is two ampersands '&&' and is used to join two conditions together. Bitwise AND is one apersand '&' and it performs an AND on the individual bits in the variable. Bitwise AND has no place in a conditional unless you are bit twiddling.

Here's a hint to an easier way:

Code :

---

char first = 'b';
char second = 'z';
System.out.println(first >= 'a' && first <= 'c');
System.out.println(second >= 'a' && second <= 'c');

Actually using a single ampersand is fine as long as you know the consequences. Run the following code.

Code :

---

class BooleanTest {
    private boolean methodOne() {
        System.out.println("Method one");
        return false;
    }
 
    private boolean methodTwo() {
        System.out.println("Method two");
        return false;
    }
 
    public void run() {
        if(methodOne() && methodTwo()) {
            System.out.println("Foo");
        }
        System.out.println();
        if(methodOne() & methodTwo()) {
            System.out.println("Foo");
        }
    }
 
    public static void main(String[] args) {
        new BooleanTest().run();
    }
}
