jAvA 按字母排序

package demo; import java.util.Arrays; public class Test { public void sortStringArray() { String[] arrayToSort = new String[] { "Oscar", "Charlie", "Ryan", "Adam", "David","aff","Aff" }; System.out.println(); System.out.printl...

你是想自己写排序算法呢还是直接用Java提供的API呢?如果想用JAVA里面的API那就推荐你用Arrays里面的sort方法,你可以为这种A--13,D--6,S--9,F--15,T--13创建一个实现Comparable接口的对象,实现里面的compareTo方法来定义你的字母所对应的大校...

public static void main (String [] args){List list = new ArrayList();Scanner scan = new Scanner(System.in);System.out.println("Please input the first name: ");list.add(getName(scan.next(),"first"));System.out.println("Please in...

char[] ch={'b','a','g','d','h','n'}; Arrays.sort(ch); System.out.println(ch);

参考代码如下 import java.util.ArrayList;import java.util.Comparator;public class ListDemo {public static void main(String[] args) {ArrayList city = new ArrayList();city.add("Jonesboro");city.add("Chaohu");city.add("LittleRock")...

import java.util.ArrayList;import java.util.List;public class Sort {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubString[] nums = { "100A", "98.5", "98.5A", "34", "52", "100", "98...

import java.util.Scanner;public class Test {public static void main(String[] args) {Scanner sc = new Scanner(System.in);System.out.println("输入一组名字: ");String s = sc.nextLine();String[] strs = s.split(" ");String temp = ""...

import java.util.Scanner;public class Test {public static void main(String[] args) {String[] words = new String[] { "a", "c", "u", "b", "e", "p", "f", "z" };System.out.print("old str : ");for (String s : words) {System.out.prin...

java是按Unicode编码的,与ASCII码是兼容的所以和ASCII码的顺序是一样的。你可以通过下面的代码来输出看一看。 public class JavaUnicode{ public static void main(String[] args) { for(char ch='a';ch

我给你个源码: public class P { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub String str="HelloWorld"; System.out.println(getUp(str)); } //功能函数 public static String getUp(St...
