your_int_value+"";
and, of course, Java Docs should be best friend in this case.
当然，在这种情况下，Java Docs 应该是最好的朋友。

There is Integer.toString()or you can use string concatenation where 1st operand is string (even empty): String snr = "" + nr;. This can be useful if you want to add more items to String variable.
有Integer.toString()或者您可以使用字符串连接，其中第一个操作数是字符串（甚至为空）：String snr = "" + nr;。如果您想向 String 变量添加更多项目，这会很有用。

a) 将整数转换为字符串
Integer one = Integer.valueOf(1);
String oneAsString = one.toString();
b) Convert an int to a String
b) 将 int 转换为 String
int one = 1;
String oneAsString = String.valueOf(one);
c) Convert a String to an Integer
c) 将字符串转换为整数
String oneAsString = "1";
Integer one = Integer.valueOf(oneAsString);
d) Convert a String to an int
d) 将字符串转换为整数
String oneAsString = "1";
int one = Integer.parseInt(oneAsString);
There is also a page in the Sun Java tutorial called Converting between Numbers and Strings.
Sun Java 教程中还有一个页面叫做Converting between Numbers and Strings。

You can use String.valueOf(thenumber)for conversion. But if you plan to add another word converting is not nessesary. You can have something like this:String string = "Number: " + 1
This will make the string equal Number: 1.
您可以String.valueOf(thenumber)用于转换。但是，如果您打算添加另一个单词，则转换不是必需的。你可以有这样的东西：String string = "Number: " + 1
这将使字符串等于 Number: 1。
