用三个线程分别计算平均值，最大值，最小值Java

package test; public class thread { public static int minValue(int a[]) { int result = a[0], i = 0; while (++i < a.length) result = Math.min(result, a[i]); return result; } public static int maxValue(int a[]) { int result = a[0], i = 0; while (++i < a.length) result = Math.max(result, a[i]); return result; } public static int averageValue(int a[]) { int result = 0, i = 0; while (i < a.length) result += a[i++]; return result / a.length; } public static void main(String[] args) { final int[] a = { 90,81,78,95,79,72,85 }; Thread t1 = new Thread() { @Override public void run() { System.out.println("the avrage value is :"); System.out.println(averageValue(a)); } }; Thread t2 = new Thread() { @Override public void run() { System.out.println("the minimum value is :"); System.out.println(minValue(a)); } }; Thread t3 = new Thread() { @Override public void run() { System.out.println("the maximum value is :"); System.out.println(maxValue(a)); } }; t1.start(); t2.start(); t3.start(); } }
