老師應(yīng)該是說(shuō)int類型成員變量的初始值為0;其他八種成員變量的默認(rèn)初始值是
For type byte, the default value is zero, that is, the value of (byte)0.?
For type short, the default value is zero, that is, the value of (short)0.?
For type int, the default value is zero, that is, 0.?
For type long, the default value is zero, that is, 0L.?
For type float, the default value is positive zero, that is, 0.0f.?
For type double, the default value is positive zero, that is, 0.0d.?
For type char, the default value is the null character, that is, '\u0000'.?
For type boolean, the default value is false.
