Question

Is there a character within the Math API that allows for representing the character π?

Answer 1

If you want to write this to a file you can achieve it through Unicodes, below is an example of how,

import java.io.*;
public class Test {

    public static void main(String[] args) throws Exception{
        BufferedWriter out = 
                    new BufferedWriter(new OutputStreamWriter(
                          new FileOutputStream("out.txt"),"UTF8"));     

    out.write("alpha = \u03B1, beta = \u03B2 ,pi = \u03C0");
    out.flush();
    out.close();
}
}

out put : alpha = α, beta = β ,pi = π
