Is it possible to get back to the Try block from a Catch block?

Question

I would like to perform validations on a config file. To do so, I have a method which will throw a MissingConfigException or an InvalidConfigException if something is missing or if something doesn't match a regex pattern. Although I have to do that with many different configs and I would like to go through all of them so that my error message will report all missing / incorrect configs at once instead of 1 at a time. Thus, I wanted to know if there would be any way I could do something like:
try {
     config.validate("ServerPort","\\d+");
     config.validate("MaxClients","\\d+");
} catch(MissingConfigException e) {
} catch(InvalidConfigException e) {
and have the catch block executed before going through the try block from where the exception was thrown.
Thanks in advance!

No, you can't jump back into the try. You can put your try/catch inside a loop though, so that if one fails, it will loop around and start a new try for the next one. Define a class that holds all the data you need to pass to validate, and make an array or List of those objects. Change or add a validate signature that takes this object, or just extract the strings from each one when you call validate.
ThingToValidate[] val = new ThingToValidate[] { new ThingToValidate("ServerPort", "\\d+"),
    new ThingToValidate("MaxClients", "\\d+"),
for (int ix = 0; ix < val.length; ix++) {
    try {
        config.validate(val[ix]);
        // OR
        config.validate(val[ix].getThingy, val[ix].getOtherThingy[]);
    catch (....) {
        // logger.warn("failed...");
