上面的代码将抛出多个char Cannot be dereferenced错误。 查看输出: Example.java:19: error: char cannot be dereferencedif(DemoString.charAt(3).equals('-') && DemoString.charAt(7).equals('-')) { ^ Example.java:19: error: char cannot be dereferencedif(DemoString.charAt(3).equals('-') && D...
java.lang.Long 是Java 中的基本数据类型 long 的包装类,用于表示长整型数值。而 java.lang.CharSequence 是一个接口,用于定义一系列字符的可读序列,例如字符串(String)实现了这个接口。 由于Long 和CharSequence 在Java 类型系统中没有继承或实现关系,因此不能直接将 Long 对象转换为 CharSequence。尝试这样做会导...

显然在Java中，不能用char参数作为分隔符调用String join，因为需要一个string。
从Java SE 5开始,可以使用Java的Instrumentation接口(java.lang.instrument)来编写Agent。无论是通过Native的方式还是通过Java Instrumentation接口的方式来编写Agent,它们的工作都是借助JVMTI来进行完成,下面介绍通过Java Instrumentation接口编写Agent的方法。 2.1.1 通过Java Instrumentation API...

Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str = "abc"; is equivalent to: char data[] = {'a', 'b', 'c'}; String str = new Stri...
