我的程序正在运行，但没有达到我想要的方式。这是我想要的输出：
C:\Documents and Settings\Joe King\My Documents\418.85A Java\Projects\Day 6>java Project3 nina pinta "santa maria"
The Nina is decreasing throttle!
The Nina is ready to launch...
but the throttle is down, increase throttle!
The Pinta is lowering the main!
The Pinta is ready to launch...
but the sail is down, hoist the main!
The Santa Maria is hoisting the main!
The Santa Maria is ready to launch...
the sail is up, ahead full!
(press ENTER to exit)
如您所见，Santa Maria已大写。这是我得到的输出：
C:\Documents and Settings\Joe King\My Documents\418.85A Java\Projects\Day 6>java Project3 nina pinta "santa maria"
The Nina is decreasing throttle!
The Nina is ready to launch...
but the throttle is down, increase throttle!
The Pinta is lowering the main!
The Pinta is ready to launch...
but the sail is down, hoist the main!
The santa maria is hoisting the main!
The santa maria is ready to launch...
the sail is up, ahead full!
(press ENTER to exit)
我的代码无法使用大写的名称字符串，例如Santa Maria。这是我的代码：
class Project3{
public static void main(String[] args){
Boat[] boatArray;
String result = " ";
char firstChar;
char firstLetter;
char secondLetter;
int i;
boatArray = new Boat[args.length];
if(args.length > 0){
for(i = 0 ; i < args.length ; i++){
String delimiters = "[ ]";
int limit = -1;
String[]tokens = args[i].split(delimiters, limit);
for( int k = 0 ; k < tokens.length ; ++k ){
if( tokens[k].length() > 1 ){
tokens[k] = tokens[k].trim();
}else{
tokens[k] = " ";
}
firstChar = tokens[k].charAt(0);
if(firstChar == ' '){
break;
}else{
if(Character.isUpperCase(firstChar)){
break;
}else{
firstChar = Character.toUpperCase(firstChar);
char[] tokenArray = tokens[k].toCharArray();
String text = new String(tokenArray, 1, (tokenArray.length - 1) );
tokens[k] = firstChar + text;
}
result = result + tokens[k];
if( k != tokens.length - 1 ){
break;
}else{
result = result.trim();
args[i] = result;
result = " ";
}
}
}
firstLetter = args[i].charAt(0);
if((firstLetter == 'B') || (firstLetter == 'C') || (firstLetter == 'N')){
boatArray[i] = new RaceBoat();
boatArray[i].christenBoat(args[i]);
}else{
boatArray[i] = new SailBoat();
boatArray[i].christenBoat(args[i]);
}
}
System.out.println("\n");
for(i = 0 ; i < args.length ; i++){
secondLetter = Character.toUpperCase(args[i].charAt(1));
if((secondLetter == 'A') || (secondLetter == 'E')){
boatArray[i].increaseSpeed();
boatArray[i].goFast();
}else{
boatArray[i].decreaseSpeed();
boatArray[i].goSlow();
}
boatArray[i].launchBoat();
boatArray[i].whatIsBoatState();
}
}else{
System.out.println("\n\nArgh!... you forgot to enter ship names scalawag!" +
"\n\n\n\tPlease try again!");
}
System.out.println("\n\n(press ENTER to exit)\n\n");
try{
System.in.read();
} catch(IOException e){
return;
}
}
}
以为问题可能是解析圣诞老人玛丽亚导致了以下问题：
' santa '
' '
' maria '
我以为这段代码会修剪它：
if( tokens[k].length() > 1 ){
tokens[k] = tokens[k].trim();
}else{
tokens[k] = " ";
}
但显然不是。我该如何完成？
最佳答案
看一下Commons-Lang StringUtils.capitalize函数。
Capizalize
您可以使用源代码，如果您想了解专业人士的制作方法，这将很有用:)
这可能使您的话大写。
StringBuilder b = new StringBuilder();
String[] parts = originalWord.split(" ");
for(String part : parts) {
String capitalized = part.substring(0, 1).toUppercase() + part.substring(1);
b.append(capitalized).append(" ");
}
//and then you can remove the last space if it is your taste.
return b.toString();
它没有基本的检查，但可以做到:)。
祝好运！
