题目:
请实现一个函数，将一个字符串中的每个空格替换成“%20”。
例如，当字符串为We Are Happy.则经过替换之后的字符串为We%20Are%20Happy
*/
public class StringDemo {
public static void main(String[] args) {
StringBuffer stringBuffer = new StringBuffer();
String str ="We Are Happy";
char[] chars = str.toCharArray();
for (int i = 0; i < chars.length; i++) {
if (chars[i] ==' '){
stringBuffer.append("%20");
}else {
stringBuffer.append(chars[i]);
}
}
System.out.println("最后的结果为: "+stringBuffer);
}
}
