Main.java void main() { int numOfApples = 16; String msg = "There are " + numOfApples + " apples"; System.out.println(msg); } The example uses string concatenation to do int to String conversion. Internally, Java compiler uses StringBuilder to do the conversion. ...

方法：调用String类的valueOf静态方法，将要转换的int类型变量作为参数传入。示例：int i = 123; String str = String.valueOf;说明：String.valueOf方法是Java中推荐的类型转换方式之一，它可以处理各种基本数据类型和对象的转换。使用StringBuilder或StringBuffer的append方法：方法：创建一个StringBuilder或Str...
// 步骤一:创建一个StringBuilder对象StringBuildersb=newStringBuilder();// 步骤二:将int类型的数值转换为String类型intnum=123;Stringstr=String.valueOf(num);// 步骤三:使用StringBuilder的append方法将转换后的String类型的数值添加到StringBuilder对象中sb.append(str); 1. 2. 3. 4. 5. 6. 7. 8. 9. ...
In this Tutorial We will see How to convert int into string in java using Integer.toString() , String.valueOf() , String.format() and StringBuffer or StringBuilder
通过查阅JVM指令码表,我们可以得知:虽然在源码中使用“+”进行字符串的连接,但是实际上在编译的时候,java是将“+”转化成了StringBuilder进行的。换句话说: //java在执行 ""+i 时,可以说简单的说是在执行以下代码: StringBuilder stringBuilder = new StringBuilder(); ...
