In a very general way:

try {

     String[] cmds = {path+"/*.exe"};
     Process proc = Runtime.getRuntime().exec(cmds);
} catch (Exception e) {

     e.printStackTrace();
}

for your question:

try {

     Process proc = Runtime.getRuntime().exec("calc.exe");
} catch (Exception e) {

     e.printStackTrace();
}
