int 是基本数据类型(面向过程留下的痕迹,不过是对java的有益补充);Integer 是一个类,是int的扩展,定义了很多的转换方法 注意:类似的还有:float Float;double Double;String等,其中String较为特殊,基本类型和复杂类似关键字相同。 例如,当需要往ArrayList,HashMap中放东西时,像int,double这种内建类型是放不进去的,...
There are three main ways to convert a long value to a String in Java e.g. by usingLong.toString(long value)method, by usingString.valueOf(long),and by concatenating with an empty String. You can use any of these methods to convert a long data type into a String object. It's not ...
1、运行速度,或者说是执行速度,在这方面运行速度快慢为:StringBuilder > StringBuffer > String 2、String为字符串常量,而StringBuilder和StringBuffer均为字符串变量,即String对象一旦创建之后该对象是不可更改的,但后两者的对象是变量,是可以更改的。对变量进行操作就是直接对该对象进行更改,而不进行创建和回收的操作,...

//一、String类方法,String.valueOf(),比如:longaa =123; String a=String.valueOf(aa);//二、最简单的直接将long类型的数据加上一个空串longaa =123; String a= aa+""; 3、String 与 Ineger 互转 (1)String 转 Integer 当我们要把String转化为Integer时,一定要对String进行非空判断,否则很可能报空...
Java example to convert long to String in two different ways using String.valueOf(long l) and Long.toString(long l) methods. Both are static methods. Java examples ofconverting alongvalue to aStringin two different ways. The first example usesString.valueOf(), and the second usesLong.toStri...
To convert a string to a long in Java, you can use the parseLong() method of the java.lang.Long class. This method parses the string as a signed decimal long, and returns the resulting long value.
String to Long Java Example Here is our sample Java program to parse String to long values. In this example, I have used different long values to demonstratehow the parseLong() method workse.g. a simple long value, a long value with a plus sign, a long value with a minus sign, and...
