Why doesn't Java have compound assignment versions of the conditional-and and conditional-or operators? (&&=, ||


Why doesn't Java have compound assignment versions of the conditional-and and conditional-or operators? (&&=, ||

I wish did fix the issue. Reason
The operators &&= and ||= are not available on Java because for most of the developers these operators are:

seems to work fine Higher precedence of assignment means that your expression evaluates to (x = 5) if false, and not to x = (5 if false). Note, that later is a perfectly valid expression too.
Whether each particular clause is executed is determined by language rules. E.g., in a ternary operator a ? b : c, only b or c will be executed, but not both.

will help you No, these operators are completely independent.
You can of course implement one using the others, but by default they're independent.
code :
struct X
{
    X& operator = (const X&);
    X operator + (const X&) const;
    //X& operator += (const X& other) 
    //        { operator=(operator+(other)); return *this; }
};

X x, y;
x += y; //doesn't compile unless you uncomment that line

seems to work fine ? and || check entirely different (but overlapping) conditions.
The || operator works exactly the same way as it does in JavaScript so things like 0 and '' are falsey as far as || is concerned; || checks truthiness in the JavaScript sense.
code :
for v in [false, 0, '', null, undefined, 6]
    do (v) ->
        a = v
        a ||= 'pancakes'
        console.log("#{v} ||= 'pancakes':", a)

for v in [false, 0, '', null, undefined, 6]
    do (v) ->
        a = v
        a ?= 'pancakes'
        console.log("#{v} ?= 'pancakes':", a)

around this issue Can anybody please tell me why this statement is giving an error - Lvalue Required , In the expression,
code :
(a > b ? g = a : g = b);
(a > b ? g = a : (g = b));
g = a > b ? a : b

wish of those help Yes you can if you wrap them in a returning function, but no you shouldn't.
In your example of the logger, let your logger output to void, discard the input when debugging isn't enabled.
