String str1=str.substring(str.length()-3);//最后三位
String str2=str.substring(0, str.length()-3);//其余的字符
}
用substring 进行分割 substring（i）表示从第几位开始切 因为字符串的起始是从0开始的，所以想切后三个，用字符串长度减1
substring （a, b） a表示其实位置， b表示长度
StringBuffer sbf = new StringBuffer("abc12ddfdf343def");
String lastString = sbf.substring(sbf.length() - 3, sbf.length());
String prevString = sbf.substring(0, sbf.length() - 3);
System.out.println(lastString);
System.out.println(prevString);
如:
String str="bcdefghigkaaa";
String str1=str.substring(str.length()-3);
String str2=str.substring(0, str.length()-3);
System.out.println(str1);
System.out.println(str2);
结果:
str1=aaa
str2=bcdefghigk
是这意思不?
