例5.7三个字符串求最大者

public class cjava {
    public static void main(String[] args) {
        System.out.println("输入三个国家的名字:");
        Scanner s = new Scanner(System.in);
        String [] strings = new String[3];
        for(int i = 0;i<strings.length;i++){
        strings [i] = s.next();
        }
        String temp = "";
        for(int i = 0;i<strings.length-1;i++){
        for(int j = 1;j<strings.length;j++)
        if(strings[i].compareTo(strings[j])<0){
        temp = strings[i];
        strings[i] = strings[j];
        strings[j] = temp;
        }
        }
        System.out.println(strings[0]);
        }
}

 例5.8 字符串从大到小排列

public class cjava {
    public static void main(String[] args) {
        System.out.println("输入三个字符串:");
        Scanner s = new Scanner(System.in);
        String [] strings = new String[3];
        for(int i = 0;i<strings.length;i++){
        strings [i] = s.next();
        }
        String temp="";
        if(strings[2].compareTo(strings[1])<0){
        temp=strings[1];
        strings[1]=strings[2];
        strings[2]=temp;
        }
        if(strings[0].compareTo(strings[1])<=0){
            System.out.print(strings[0]+" "+strings[1]+" "+strings[2]);
            }
        else if(strings[0].compareTo(strings[2])<=0){
            System.out.print(strings[1]+" "+strings[0]+" "+strings[2]);
            }
        else System.out.print(strings[1]+" "+strings[2]+" "+strings[0]);
}
        
}
