Java 数组排序

一维数组的排序

使用Arrays.sort()对数组排序

　　适用于数值型数组 byte/char/short/int/long/float/double

public class Test {
    
    public static void main(String[] args) {
        int[] a = {15,67,51,34,12,99,13,65};
        
        Arrays.sort(a);
        //for-each
        for (int i : a) {
            System.out.print(i + "\t");
        }
        //for
//        for (int i = 0; i < a.length; i++) {
//            System.out.print(a[i] + "\t");
//        }
    }
}

　　适用于String型数组（暂时省略）

public class Test {
    
    public static void main(String[] args) {
        String[] b = {"zdfg","asf","ert","dfg","tyjy","cgef"};
        
        Arrays.sort(b);
        //for-each
        for (String i : b) {
            System.out.print(i + "\t");
        }
    }
}
