Itterate over String-CodePudding

So, I have this problem:

    #!/usr/bin/env groovy
    
    package com.fsfs.fdfs.fsf.utils
    
    class GlobalVars {
        // TEST-DEV
        static String MY_URL1 = "https://myurl.com"
        static String MY_URL2 = "https://:6443"
        static String MYURLS_TEST = "${MY_URL1} ${MY_URL2}"

}

So I want to itterate over my URLS depending on the environment. For example: in this ENV is TEST , but could be DEV, PROD and so on

 for( Name in GlobalVars."MYURLS_${ENV}".split(/\s /)) {

    }

I'm not sure how to achieve this. Basically, I want to iterate over a variable with a dynamic name. The variable contains at least 2 strings

CodePudding user response：

You can look into CharacterIterator methods current() to get the current character and next() to move forward by one position. StringCharacterIterator provides the implementation of CharacterIterator.

or for a simpler task can

Create a while loop that would check each index of the string or a for loop like this

 for (int i = 0; i < str.length(); i  ) {
 
            // Print current character
            System.out.print(str.charAt(i)   " ");
        }

Iterating Strings works out of the box in Groovy:

"bla".each{println it}

.each{} closure will go over all characters of the string.

Same can be achieved with a more classical for-loop:

for(c in "foo") println c

Either way should work.
