hop of those help? Assuming getFoo() returns an the array foo (which seems to be the case from your for loop statement), you can access index x of foo with:
code :
int a = getFoo()[x];
int[] foo = getFoo();
for(int x = 0; x < foo.length; x++){
    int a = foo[x];
    //do stuff with a
}
for(int a : getFoo()){
    //do stuff with a
}

will help you All your fields in class who are static, hence all instances of class who will share the same data (i.e. have the same name, the same IP, etc.). Using static in this context does not make sense.

Java XML Parsing, read's values into array correctly then overwrites entire array with last values?

This might help you I'm making a simple game, and loading an XML file with weapon stats into an array of weapons to be used in game. The stats and weapon objects are all correctly read and populated until the 'try' statement ends and then the entire array of weapons is re-written with the values of the last read weapon element. I can not for the life of me figure out why it decides to re-write everything suddenly, help would be greatly appreciated as I feel it's a rookie mistake! , You need to create a new stats array inside the loop.

I wish this helpful for you Here's my array (from Chrome console): , Here is the minimal amount of javascript to reproduce the issue
code :
var test = [];
test["11h30"] = "15h00"
test["18h30"] = "21h30"
console.log(test);    
console.log(JSON.stringify(test)); // outputs []
var test = {}; // here is thre only change. new array ([]) becomes new object ({})
test["11h30"] = "15h00"
test["18h30"] = "21h30"
console.log(test);
console.log(JSON.stringify(test)); // outputs {"11h30":"15h00","18h30":"21h30"}

this one helps.
Here's a way to do this using pyspark.sql.functions.regexp_replace() and a simple loop:
code :
data = [
    ("I have been working here as a store manager.",),
    ("I am sales manager.",),
    ("I joined as an IT analyst and was promoted to IT manager.",)
]

df = sqlCtx.createDataFrame(data, ["current_title"])
df.show(truncate=False)
#+---------------------------------------------------------+
#|current_title                                            |
#+---------------------------------------------------------+
#|I have been working here as a store manager.             |
#|I am sales manager.                                      |
#|I joined as an IT analyst and was promoted to IT manager.|
#+---------------------------------------------------------+
import pyspark.sql.functions as f

keyword = ['IT Manager', 'Sales Manager', 'IT Analyst', 'Store Manager']
lookupid = ['##10##','##13##','##12##','##13##']

for k, replacement in zip(keyword, lookupid):
    pattern = r'\b(?i)' + k + r'\b'
    df = df.withColumn(
        'current_title',
        f.regexp_replace(f.col('current_title'), pattern, replacement)
    )
df.explain()  
df.show(truncate=False)
#+-------------------------------------------------+
#|current_title                                    |
#+-------------------------------------------------+
#|I have been working here as a ##13##.            |
#|I am ##13##.                                     |
#|I joined as an ##12## and was promoted to ##10##.|

How to append entire second array to first array in java

Does that help Guava provides Arrays.concat(T[], T[], Class).
The reason for the Class parameter, FYI, is because generic arrays have a distinct tendency to get upcast. If you did Arrays.concat(Integer[], Long[]), did you want an Object[] back? Or a Number[]? Guava makes you specify so there's no ambiguity...and because all of the alternatives can lead to unpredictable ClassCastExceptions at runtime.
