The Selection Sort coded below does not sort correctly. The numbers 7,66,5,40,33,99 are entered into an array called nums[]. When the program is run they do not sort from low to high? Certain sequences will sort, such as 10,9,8,7,6,5 but not all random sequences of six integers.  
I have reviewed the code many time but can not solve the problem.  
Can some one help me out?

int temp = 0;

int[] nums = {7,66,5,40,33,99};

void setup() {  
size(1000,1000);  
background(255);  
textSize(50);  
fill(255,0,0);

for(int i = 0; i \< nums.length; i++){  
text("["+i+"]",100 + 100 \* i, 60);  
text(nums[i],100 + 100 \* i, 120);  
}  
}

void draw(){  
fill(0,0,255);  
for (int i = 0; i \< nums.length-1; i++) {  
// Find the minimum element in unsorted array  
int min = i;  
for (int j = i+1; j \< nums.length; j++) {  
if (nums[j] \< nums[min]) {  
min = j;

```
        // Swap the found minimum element with the first 
        // element 
        int temp = nums[min]; 
        nums[min] = nums[i]; 
        nums[i] = temp; 
    } 
} 
    }

```

fill(255,0,0);  
for(int i = 0; i \< nums.length; i++){

```
  text(nums[i], 200+100*i, 780);
  text("["+i+"]",200 + 100 * i, 700);

```

}  
noLoop();  
}

Hi @Brucef,

Welcome to the forum!

Do you need to build the sort function yourself?  
If not, take a look at the Arrays.sort() method
