package cn.jbit.array;

public class Insert {

	public static void main(String[] args) {
		//字符排序

		System.out.print("原字符序列:");
		for(int i = 0; i < chars.length; i++){
			System.out.print(chars[i] + " ");
		}
		Arrays.sort(chars);		//对数组进行升序排序
		System.out.print("\n升序排序后:");
		for(int i = 0; i < chars.length; i++){
			System.out.print(chars[i] + " ");
		}
		
		//实现插入字符
		int index = chars.length;	//保存新增成绩插入位置
		char ch='m';
		System.out.println("\n待插入的字符是: "+ch);
	
		//找到新元素的插入位置
        for(int i = 0; i < chars.length; i++){
            if(ch < chars[i]){
                index = i;
                break;
            }
        }			
		 //元素后移
        for(int j = chars.length-1; j > index; j--){
        	chars[j] = chars[j-1];	//index下标开始的元素后移一个位置
        }
        chars[index] = ch;//插入数据
		System.out.println("插入字符的下标是:"+index);
		System.out.print("插入后的字符序列是: ");
		for (int k = 0; k < chars.length; k++) { // 循环输出目前数组中的数据
			System.out.print(chars[k] + " ");
