void main() { int numOfApples = 16; String msg = String.format("There are %s apples", numOfApples); System.out.println(msg); } The example uses String.format to do int to String conversion. Using string concate
The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings. String concatenation is implemented through the StringBuilder(or StringBuffer) class and its append method. String conversions are implemented through the method toStr...

方法一:使用String.valueOf() 最直接的方法是使用Java内置的String类中的valueOf()方法。这是一个静态方法,可以接收各种基本数据类型,包括int,并将其转换为对应的字符串。 intnumber=123;StringstrNumber=String.valueOf(number);System.out.println("使用 String.valueOf() 转换结果: "+strNumber); 1. 2. 3...
public class JavaExample{ public static void main(String args[]){ String str=”123″; int inum = 100; /* converting the string to an int value * ,the value of inum2 would be 123 after * conversion */ int inum2 = Integer.parseInt(str); ...
在java中,大家肯定都会遇到int类型转String类型的情形,知其然知其所以然。总结加分析一下,int类型转String类型有下面几种方式: 1.a+”“2.String.valueOf(a)3.Integer.toString(a) 1. 2. 3. 以上三种方法在实际使用过程中都是没有问题的,可是效率上还是有些许区别的,所以写个小程序来对照一下他们的效率:...

In Java, converting an int value to String is not difficult, but knowing which method may save us a few CPU cycles is worth knowing.
手动编码更佳。这是最直接的方式,基于Java标准库。该函数接受int参数,返回无前缀的二进制字符串表示,32位格式(补0到32位)。名称"toBinaryString"来源于Java核心类,设计目的是简化数据输出。优点是简单高效,O(1)时间复杂度;但缺点是处理负数时直接显示补码,可能导致新手误读。接下来是详细实施步骤。
Example 1: Java Program to Convert string to int using parseInt() class Main { public static void main(String[] args) { // create string variables String str1 = "23"; String str2 = "4566"; // convert string to int // using parseInt() int num1 = Integer.parseInt(str1); int ...
