Here are four different ways you can use to convert an int to String in Java. Most of them are very similar to what we have used to convert an Integer to a String because you can easily convert an int to Integer using Autoboxing. Some method reuses each other like valueOf(), which i...
To convert a int to string: int num = 123; String str = String.valueOf(num); To convert a string to int: String str = "123"; int num = Integer.valueOf(str); 版权声明:本文为博主原创文章,未经博主允许不得转载。
The example uses string concatenation to do int to String conversion. Internally, Java compiler usesStringBuilderto do the conversion. Java int to String with Integer.toString Integer.toStringconverts its argument to signed decimal representation and returned as a string. Main.java void main() { in...
public static void main(String[] args) { // create int variable int num1 = 36; int num2 = 99; // convert int to string // using valueOf() String str1 = String.valueOf(num1); String str2 = String.valueOf(num2); // print string variables System.out.println(str1); // 36 ...
String myString = ""; Step 3 Convert the integer to a string. Now the integer can be converted. This line of code converts the myInteger variable and saves it to the myString value: Advertisement myString = Integer.toString(myInteger); ...
第一种方法:s=i+""; //会产生两个String对象 第二种方法:s=String.valueOf(i); //直接使用String类的静态方法,只产生一个对象 第一种方法:i=Integer.parseInt(s);//直接使用静态方法,不会产生多余的对象,但会抛出异常 第二种方法:i=Integer.valueOf(s).intValue();//Integer.valueOf(s) 相当于 ne...
1、int i = Integer.parseInt([String]);或i = Integer.parseInt([String],[int radix]); 2、int i = Integer.valueOf(my_str).intValue(); 注: 字串转成 Double, Float, Long 的方法大同小异. 2 如何将整数 int 转换成字串 String ?
类比C#中的Convert.ToInt32()方法，Integer.parseInt()同样支持额外参数，用于指定转换的数字进制。例如：这段代码将字符串"11"转换为二进制数3。综上，想要在Java中实现与C#中Convert.ToInt32()方法类似的功能，只需采用Integer.parseInt()方法并适当处理可能出现的异常即可。
public class Main { static String Str( String A,String B,int Inte ) { if( Inte == 1 ) { return A + B; } return ""; } public static void main(String[] args) { System.out.println( Str("aaa","bbb",1)); }}if( Inte == 1...
to convert long values to String in Java. It's better to useLong.toString()method because all other methods internally call this one only. If you know how to convert int to String or double to String, you can follow the same steps to convert other data types to String in Java as ...
