When used with boolean operands, the&operator behaves like the&&operator, except that it always evaluates both operands, regardless of the value of the first operand. This operator is almost always used as a bitwise operator with integer operands, however, and many Java programmers would not even...
The AND operator results in false when one operand is false, no matter what the second operand is. If you use the || and &&, Java will not evaluate the right-hand operand when the outcome can be determined by the left operand alone. ...

在Java编程中,遇到错误“operator '||' cannot be applied to 'boolean', 'java.lang.String'”时,这通常意味着你尝试将逻辑或运算符||应用于不兼容的数据类型:一个是布尔类型(boolean),另一个是字符串类型(java.lang.String)。下面是对此问题的详细解答: '||' 操作符在 Java 中的用法: || 是Java 中...
