if statement not working.Whats wrong with my code?

I'm a beginner with java and I dont know whats wrong with my code. Your assistance will be highly appreciated.

int pay1  = 190;
int pay2  = 1175;
int pay3  = 455;
int pay4  = 345;
int tc    = 400;
int[] pay = { pay1, pay2, pay3, pay4 };

for(int i = 0; i < pay.length; i++)
{
    if(pay[i] < tc)
    {
        pay[i] = pay[i]++;
        System.out.println(pay[i]+",");
    }
    else
    {
    }

// I.e if any element of the array is less than tc, then its value should be incremented.
