Integer.toString converts its argument to signed decimal representation and returned as a string. Main.java void main() { int numOfApples = 16; String msg = "There are " + Integer.toString(numOfApples) + " apples"; System.out.println(msg); } ...
intnum=100;Stringvalue1=Integer.toString(num);// Works for Integer tooStringvalue2=String.valueOf(num);// Works for Integer too 1. UsingInteger.toString() TheInteger.toString(int)returns a string representing the specifiedintpassed as a method argument. By default, the argument is converted t...
1、String s = String.valueOf(i); 2、String s = Integer.toString(i); 3、String s = "" + i; 注: Double, Float, Long 转成字串的方法大同小异. int -> String int i=12345; String s=""; 第一种方法:s=i+""; 第二种方法:s=String.valueOf(i); 这两种方法有什么区别呢?作用是不是...

使用Integer.toString是最优的选择,就像原文所说的 It is not that one need to optimize everything to this level, but learning a few good habits like this will help in the long run. String -> int/Integer 两种写法 int i = Integer.parseInt("43"); ...
We can also convert the string variables into an object of Integer using the valueOf() method. For example, class Main { public static void main(String[] args) { // create string variables String str1 = "643"; String str2 = "1312"; // convert String to int // using valueOf() ...
System.out.println(StringUtils.join(intList,"|")); }Copy Output: 1|2|3Copy Again, this implementation is internally dependent on thetoString()implementation of the type we’re considering. 5. Conclusion In this article, we learned how easy it is to convert aListto aStringusing different te...
