如何使用Java从字符串中提取前n个字符？
要在给定的String中找到辅音，请使用charAt()方法将其中的每个字符与元音字母进行比较，其余为辅音。
示例
public class FindingConsonants {
public static void main(String args[]) {
String str = new String("Hi Welcome to Nhooo");
for(int i=0; i<str.length(); i++) {
if(str.charAt(i) == 'a'|| str.charAt(i) == 'e'|| str.charAt(i) == 'i' ||
str.charAt(i) == 'o' || str.charAt(i) == 'u'|| str.charAt(i) == ' ') {
}else{
System.out.println("Given string contains "+str.charAt(i)+" at the index "+i);
}
}
}
}输出结果
Given string contains H at the index 0 Given string contains W at the index 3 Given string contains l at the index 5 Given string contains c at the index 6 Given string contains m at the index 8 Given string contains t at the index 11 Given string contains T at the index 14 Given string contains t at the index 16 Given string contains r at the index 18 Given string contains l at the index 21 Given string contains s at the index 22 Given string contains p at the index 23 Given string contains n at the index 26 Given string contains t at the index 27
