Java program to convert a Long to String //Java code to convert along to StringpublicclassMain{publicstaticvoidmain(Stringargs[]){longa=112120;longb=2121210;//variable to store resultStringresult=null;//converting long to stringresult=Long.toString(a);System.out.println("result (value of a ...
Stringstr1=String.valueOf(l);Stringstr2=String.valueOf(obj); Whenobjisnull, the method will setstr2to “null” instead of throwing aNullPointerException. 4. UseString.format() Besides thevalueOf()method of theStringclass, we can also use theformat()method: Stringstr1=String.format("%d"...
String.format()was introduced in java 5. We can use this method to convert a long value to String as shown in the following program. publicclassJavaExample{publicstaticvoidmain(Stringargs[]){longl=1234567L;Stringstr=String.format("%d",l);//Output: "1234567"System.out.println("long to St...
day= TypeChange.stringToDate("2003-11-3"); String strday=TypeChange.dateToString(day); System.out.println(strday); } } 二、Java对象与Json字符串间的相互转换 (1)简单的解析json字符串 //首先将json字符串转换为json对象,然后再解析json对象,过程如下。JSONObject jsonObject =JSONObject.fromObject(json...
StringlongString="This is a very long string that needs to be processed in parts";intchunkSize=10;for(inti=0;i<longString.length();i+=chunkSize){Stringchunk=longString.substring(i,Math.min(i+chunkSize,longString.length()));// process the chunk} ...
//Java code to convert String to Long public class Main { public static void main(String args[]) { String str = "1234587878"; //variable to store result long result = 0; //converting string to long //method 1 result = Long.valueOf(str).longValue(); System.out.println("result (...
因为Sting是这样定义的:public final class String extends Object,里边有final关键字,所以不能被继承。 1、在Java中,只要是被定义为final的类,也可以说是被final修饰的类,就是不能被继承的。 2、final是java中的一个关键字,可以用来修饰变量、方法和类。用关键词final修饰的域成为最终域。用关键词final修饰的变...
[Java] int,char,long类型转String 虽说这是一个很简单的问题, 但我今天碰到的时候竟然忘记了. 返回给前端的JSON格式是数型而非需求文档要求的字符串. 1. String.valueOf(param); 2. 空字符串,param+""
