JAVA中如何用array类中的sort排序方法实现数组排序

public static void main(String[] args) {
int[] iii={4,5,61,3,2,4,26,21,2,-82,34};
Arrays.sort(iii);
for (int i : iii) {
System.out.println(i);
}
}

public class testjava {
public static void main (String args[]) {
int src[] = {4, 5, 2, 88, 3, 99, 88, 55};
java.util.Arrays.sort(src);
int i=src.length;
System.out.println("第二大的数是：" + src[i-3]);
for(i=0;i System.out.print(src[i]+"\t");
}
}
}

package ch03;
import java.io.*;
import java.util.ArrayList;
import java.util.List;

public class JavaBean {

//输出属性
public static void variable(PrintWriter pw,String value )
{
pw.println(" private "+value+";");
}

//输出有参构造器代码块
public static void parameter(PrintWriter pw,String value )
{
pw.println(" this."+value+"="+value+";");
}

//每个属性创建Getters和Setters方法
public static void middle(PrintWriter pw,String middle1,String middle2)
{
//将首字母转换大写转换
char c=middle2.charAt(0);
char d=Character.toUpperCase(c);
String caps = middle2.replace(c, d);

pw.println(" public "+middle1+" get"+caps+"(){"+"\r\n"
+" return "+middle2+";"+"\r\n"
+" }"
+"\r\n"
+" public void"+" set"+caps+"(){"+"\r\n"
+" }"
+"\r\n");
}
