Shell script and java parameter

I have written the script run.sh below for calling a java class : ``` java -cp . Main $1 $2 $3 $4 ``` Here is my java class (it just displays the args) : ``` public class Main { public static void main(String[] args) { for (String arg : args) { System.out.println(arg); } } } ``` This is working unless I try to pass a parameter containing a space. For example : ``` ./run.sh This is "a test" ``` will display : ``` This is a test ``` How could I modify my shell script and/or change my parameter syntax to pass the parameter "a test" unmodified ?
