It depends on what you mean by "convert an int to char".

If you simply want to cast the value in the int, you can cast it using Java's typecast notation:

<pre><code>int i = 97; // 97 is 'a' in ASCII
char c = (char) i; // c is now 'a'
</code></pre>

If you mean transforming the integer 1 into the character '1', you can do it like this:

<pre><code>if (i &gt;= 0 &amp;&amp; i &lt;= 9) {
char c = Character.forDigit(i, 10);
....
}
</code></pre>

This solution works for Integer length size =1.

<code>Integer input = 9;
Character.valueOf((char) input.toString().charAt(0))</code>

if size >1 we need to use for loop and iterate through.

Basing my answer on assumption that user just wanted to literaaly convert an <code>int</code> to <code>char</code> , for example 

<pre><code>Input: 
int i = 5; 
Output:
char c = '5'
</code></pre>

This has been already answered above, however if the integer value <code>i &gt; 10</code>, then need to use <code>char array</code>.

<pre><code>char[] c = String.valueOf(i).toCharArray();
</code></pre>

The answer for conversion of char to int or long is simple casting.

For example:- if you would like to convert Char '0' into long.

Follow simple cast

<pre><code>Char ch='0';
String convertedChar= Character.toString(ch); //Convert Char to String.
Long finalLongValue=Long.parseLong(convertedChar);
</code></pre>

Done!!

This has probably been answered else where but how do you get the character value of an int value?

Specifically I'm reading a from a tcp stream and the readers .read() method returns an int.

How do I get a char from this?

Converting stream of int's to char's in java

Java

这个问题可能已经回答了，但是如何获得int值的字符值呢？具体地说，我从tcp流中读取，读取器.read()方法返回一个整数。我怎样才能从中得到一个字符呢？
