把C代码转换成Java代码如下：

import java.util.Scanner;

public class Main {
static int n, ans, k, coe, len, outcome;
static int[] c = new int[10011];
static char[] e = new char[10011];
static char[] s = new char[10011];

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
n = sc.nextInt();
e = sc.next().toCharArray();
ans = calculate();
System.out.println(ans);
sc.close();
}

static void sort(int x) {
int i, j, t;
for (i = 1; i < x; i++) {
for (j = i + 1; j > 1; j--) {
if (c[j] < c[j - 1]) {
t = c[j - 1];
c[j - 1] = c[j];
c[j] = t;
} else {
break;
}
}
}
}

static int calculate() {
int i, j;
k = outcome = 0;
len = e.length;

if (e[0] != '-') {
for (i = len + 1; i > 0; i--) {
s[i] = s[i - 1];
}
s[0] = '+';
len++;
} else {
s = e.clone();
}

for (i = 0; i < len; i += 3) {
if (s[i] == '+') {
coe = 1;
} else {
coe = -1;
}

i++;
j = 0;
while ('0' <= s[i] && s[i] <= '9') {
j *= 10;
j += s[i++] - '0';
}

if (s[i] == '*') {
i++;
} else {
j = 1;
}

coe *= j;
c[++k] = coe;
outcome += (n - (s[i] == 'a')) * coe;
}

sort(k);
for (i = 1; i <= k; i++) {
outcome += i * c[i];
}

return outcome;
}
}
