例5.7三个字符串求最大者

 1 public class cjava {
 2     public static void main(String[] args) {
 3         System.out.println("输入三个国家的名字:");
 4         Scanner s = new Scanner(System.in);
 5         String [] strings = new String[3];
 6         for(int i = 0;i<strings.length;i++){
 7         strings [i] = s.next();
 8         }
 9         String temp = "";
10         for(int i = 0;i<strings.length-1;i++){
11         for(int j = 1;j<strings.length;j++)
12         if(strings[i].compareTo(strings[j])<0){
13         temp = strings[i];
14         strings[i] = strings[j];
15         strings[j] = temp;
16         }
17         }
18         System.out.println(strings[0]);
19         }
20 }

 

 例5.8 字符串从大到小排列

 1 public class cjava {
 2     public static void main(String[] args) {
 3         System.out.println("输入三个字符串:");
 4         Scanner s = new Scanner(System.in);
 5         String [] strings = new String[3];
 6         for(int i = 0;i<strings.length;i++){
 7         strings [i] = s.next();
 8         }
 9         String temp="";
10         if(strings[2].compareTo(strings[1])<0){
11         temp=strings[1];
12         strings[1]=strings[2];
13         strings[2]=temp;
14         }
15         if(strings[0].compareTo(strings[1])<=0){
16             System.out.print(strings[0]+" "+strings[1]+" "+strings[2]);
17             }
18         else if(strings[0].compareTo(strings[2])<=0){
19             System.out.print(strings[1]+" "+strings[0]+" "+strings[2]);
20             }
21         else System.out.print(strings[1]+" "+strings[2]+" "+strings[0]);
22 }
23         
24 }
