主要用到以下函数
package dishiyitian;
public class lianxi {
public static void main(String[] args) {
// TODO Auto-generated method stub
// text1();
text2();
}
private static void text2() {
// TODO Auto-generated method stub
String name="fdfd;feit.texfd;hellow.yuyu;hellow.php";
String name1=name.substring(0,1).toUpperCase();
String name2=name.substring(1);
System.out.println(name1+name2);
}
private static void text1() {
// TODO Auto-generated method stub
String name="fdfd;feit.texfd;hellow.yuyu;hellow.php";
String[] name1=name.split(";"); //注意实现要求数组
for(String n:name1)
{
if(n.startsWith("hellow"))
{
System.out.println(n);
int i=n.lastIndexOf(".");
System.out.println(n.substring(i));
}
}
}
}
实现结果如下
hellow.yuyu
.yuyu
hellow.php
.php
Fdfd;feit.texfd;hellow.yuyu;hellow.php
