when I return an array, I get a "cannot find symbol" error

I am creating a program where the user (teacher) enters a bunch of percentage grades, and these grades get analyzed, and an outputBox prints out the average, min/max, range, and the number of grades that are 'Level R', 'Level 1', 'Level 2' and so on.

The problem I am facing is the method which sorts the grades into different levels. When I try to return my array to the main method, and try to print it to my output, I get an error for the array, saying "cannot find symbol"

import java.util.Arrays.*;



public Integer[] Levels(){
Integer[] levelCount = {0,0,0,0,0};
int mark = Integer.parseInt(markInput.getText());

int i;
for (i=0; i<levelCount.length;i++ )
{
    if (mark <50){
        levelCount[0] = levelCount[0]+1;
    }
    else if ((mark >= 50) && (mark <60)){
        levelCount[1] = levelCount[1]+1;
    }
    else if ((mark >=60) && (mark<70)){
        levelCount[2] = levelCount[2]+1;
    }
    else if ((mark >=70)&&(mark<80)){
        levelCount[3] = levelCount[3]+1;
    }
    else if ((mark >=80) && (mark<=100)){
        levelCount[4] = levelCount[4]+1;

    }
}

return levelCount;

so, when I go to my main method to print out all the information, I am supposed to put the levelCount array into ANOTHER array, which I did. Here is what I have:

String [] level = {"\nNumber at Level R: " + Levels(levelCount[0]), 
"\nNumber at Level 1: " +Levels(levelCount[1]), 
"\nNumber at Level 2: " + Levels(levelCount[2]), 
"\nNumber at Level 3: " + Levels(levelCount[3]),
"\nNumber at Level 4: " + Levels(levelCount[4])};

So my grand dilemma, is that the array levelCount shows the error 'cannot find symbol'. No matter what I try, I continue getting this error.

I feel like the answer is extremely obvious, but I searched online for something that would help me with this problem, and nothing seems to work, I keep getting the same error.

Your method Levels does not take any argument, so when you try to create the String array in the main method, that won't compile. Your Levels method returns String[] as well. Try changing the use of the method like this:

int[] levelCount = Levels();    
String [] level = {"\nNumber at Level R: " + levelCount[0], 
"\nNumber at Level 1: " + levelCount[1], 
"\nNumber at Level 2: " + levelCount[2], 
"\nNumber at Level 3: " + levelCount[3],
"\nNumber at Level 4: " + levelCount[4]};

And change the array to int or Integer as proposed by Asfab.

Change line Integer[] levelCount = {0,0,0,0,0}; to

Integer[] levelCount = {0,0,0,0,0,0};

Or remove levelCount[5] = levelCount[5]+1;

In the above line you are trying to read 6th (index 5) element , but your declared Array size is 5 (i.e max index 4)
