Java是一種高級編程語言，可以用來計算整數和負數的個數。以下是一個簡單的Java程序來計算整數和負數的個數。

import java.util.Scanner;
public class CountIntegersAndNegatives {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int positives = 0;
int negatives = 0;
int count = 0;
double total = 0;
System.out.print("Enter an integer, the input ends if it is 0: ");
int number = input.nextInt();
if (number == 0) {
System.out.println("No numbers are entered except 0");
System.exit(1);
}
while (number != 0) {
if (number >0)
positives++;
else
negatives++;
total += number;
count++;
number = input.nextInt();
}
double average = total / count;
System.out.println(
"The number of positives is " + positives +
"\nThe number of negatives is " + negatives +
"\nThe total is " + total +
"\nThe average is " + average);
}
}

在這個程序中，我們使用Scanner類從控制臺讀取整數，并使用while循環根據輸入的數字進行計算。如果輸入的數字是正數，則增加計數器“positives”的值，如果輸入的數字是負數，則增加計數器“negatives”的值。最后輸出計數器的值和平均值。
