StringBuffer String String[]

String[]

 

String[] attA={"width","align","type","sort","id"};   
   for(String s:attA){   
s=s+"---";   
   }   
   for(String s:attA){   
ystem.out.println(s);   
   }  

 

结果：

width   
align   
type   
sort   
id

1:删除最后一个字符:

StringBuffer sbf=new StringBuffer("china");   
sbf.delete(sbf.length()-1, sbf.length());   

 2:替换最后一个字符

sbf.replace(sbf.length()-1, sbf.length(), "x");

删除最后一个字符:
sbf.deleteCharAt(sbf.length()-1);

替换最后一个字符:
sbf.setCharAt(sbf.length()-1,'x');
