java编写一个程序,读入一个英文句子,分别统计出其大写和小写字母

importjava.util.Arrays;importjava.util.Scanner;importjava.util.StringTokenizer;publicclassTest{publi

publicclassPrintUpperChar{publicstaticvoidmain(String[]args){for(charM='Z';M>='A';M--){System.out.pr

首先要分析业务逻辑:打印10行的三角 第0行打印10个空格,  打印1个*   打印0个空格,  (打印0个*此处判断,

楼上的两个答案都不对.都忘了将n-1.publicclassTestNFactorial{publicstaticvoidmain(String[]args){inttarget=9876;run(t

publicclassTest{publicstaticvoidmain(String[]args){intsum=0;inti=2;while(i

importjava.util.regex.Matcher;importjava.util.regex.Pattern;publicclassTest{publicstaticvoidmain(Str

staticvoidBubbleSort(inta[]){inttemp=0;for(inti=0;ifor(intj=0;jif(a[j]>a[j+1]){//把这里改成大于,就是升序了temp=a

importjava.util.Scanner;publicclassTriangle{publicstaticvoidmain(String[]args){\x09inta;\x09intb;\x0

楼上的方法应该没错,可感觉对于表现java面向对象的特性没有表现出来,下面是我写的,应该非常清楚明了了importjava.io.BufferedReader;importjava.io.InputS

publicstaticStringtranslate(Stringvalue){StringBufferresult=newStringBuffer();char[]valueChars=value

test{publicstaticvoidmain(Stringargs[]){longsum=0,a=1;longi=1;while(i=1)sum=sum+a;i++;a=a*i;}System.

请问,每个人的英语课的成绩哪里来?再问：就是自己输入Scanner再答：看看符合你的要求不
