If I have a string.
String msg = "I love mickey mouse";
What method can I used to display the string, "mickey"?
Jump to PostLooking at the Javadoc for the String class and finding the required method would be a good exercise for you.
Jump to PostRead the API doc for the split() method.
Where (what index) in the array returned by split() would the desired word be?
Jump to PostUse subString() method...
See the documentation for method signature...

I will use indexOf(). Is it correct?
Try to read documentation for the method public String substring(int beginIndex, int endIndex)
我会用 String[] split(String regex) 得到一个关于这个字符串的字符串数组
public String getStringMickey(){
String msg = "I love mickey mouse";
String[] str = msg.split(" ");
return str[2];
}
subString
我会用 String[] split(String regex) 得到一个关于这个字符串的字符串数组
public String getStringMickey(){ String msg = "I love mickey mouse"; String[] str = msg.split(" "); return str[2]; }
Why str[2]?
Read the API doc for the split() method.

不知道楼上的意思是什么,回答引用人的问题:
String str[] = msg.split(" ");
这里的str是一个String数组,里面装的是{"I","love","mickey","mouse"}
now, do u know why str[2] 了吗?
Use subString() method...
