Array in an Array [duplicate]

I want to know if it possible to handle an array in another array, i never heard of something like that and i'm curious if it is possible, because i'm writing a little programm rigth now and i would need something like this! An example(maybe this can be solved other than using an array in an array): i have two String arrays like this:

public String[] stringArray1 = { "0", "1", "2", "3" }, stringArray2 = { "0", "1", "2", "3" };

now i would need something like this:

public /*type?*/[] allArrays = { stringArray1, stringArray2 };

because i need to access it using an for loop and i dont want to use thousands of if statements to get to the stringArrays(this is just an example in my real programm there are like 100 arrays):

for(int i = 0; i < numberOfArrays/*100*/; i+=2)
test/*a rondom void*/(allArrays[i], allArrays[i+1]);

in my programm there are always two arrays connected that's why i call one with i and one with i+1... so now this is how my test looks like:

public void test(/*type?*/ test1, /*type?*/ test2)
{
//now i need to use test1 & test2 as string to f.e. like this:
if(test1[2].contains("1"))
//do something
}
