Java String args asterisk

How can Java take an * from String args and print it out. I tried handling it with the commented portion of this code but it did not work.

Input: 1430 - 110 * 2A + 10

Outputs: 1430-110.classpath.project.settingsbinsrc2A+10

import java.io.*;

public class Main {

/**
 * @param args
 */
public static void main(String[] args) {
    for(int i=0; i<args.length; i++) {
        System.out.print(args[i]);

        /*

        if(args[i].equals(".classpath.project.settingsbinsrc")) {
            args[i] = "*";
        }

        */

    }

}

}

Your shell expands the asterisk (*) to the list of files in your current directory. You should embrace your arguments by quotation marks to avoid that:

Input: "1430 - 110 * 2A + 10"

I think You are looking for something like this:

public static void main(String[] args)  {
    String str = "";
    for(int i=0; i<args.length; i++) {
        System.out.print(args[i]);
        str=str.concat(args[i]);
    }
    str = str.replaceAll(".classpath.project.settingsbuildejbModule", "*");
    System.out.println();
    System.out.println(str);

}
