;代替public PrintStream format(String format, Object… args) 当多个参数输出的时候可以这样使用: System.out.format("The value of " + "the float variable is " + "%f, while the value of the " + "integer variable is %d, " + "and the string is %s", floatVar, intVar, stringVar); 对于...
• 不能够对final变量再次赋值,final方法不能被重写,final类不能被继承。 • 没有在声明时初始化final变量的称为空白final变量(blank final variable),它们必须在构造器中始化,或者调用this()初始化。 • 使用 final 关键字修饰一个变量时,是指引用变量不能变,引用变量所指向的对象中的内容还是可以改变的 ...
Internally, these objects are treated like variable-length arrays that contain a sequence of characters. At any point, the length and content of the sequence can be changed through method invocations. Strings should always be used unless string builders offer an advantage in terms of simpler code...
