感觉没什么实际意思.1=1是恒等.你得把代码上下文都贴出来,个人感觉,应该是为了方便拼接代码.
举个例子.
sbwhere=“ 1=1 ”;
for(...)

sbwhere+= " and deleted='0'";
}
这时候sb=“1=1”;就有必要了,这样即便for循环为空,也不会因为where或and关键字的影响而报错.
StringBuffer sb = new StringBuffer(); sb.append(endDate.substring(5,7)); endDate.substring(5,7)这句是啥意思啊

定义了StringBuffer数组,为什么还要创建string buffers如下程序:public class ThisHappens {public static void main(String[] args) {StringBuffer[] stringBuffers = new StringBuffer[10];for (int i = 0; i < stringBuffers.length; i ++) {strin
String aa,b,c; aa=”bb”; b=”dd”+aa; c=”cc”+b+aa; StringBuffer d = new StringBuffer(c);请问总共创建了多少个对象?求具体解释.
public class Foo { public static void main(String[] args) { StringBuffer a=new StringBuffer(A);问下这里的a怎么和“A‘’,b怎么和''B相等的
StringBuffer sb2=sb1;是什么意思那sb1==sb2与sb1=sb2有什么不同么?
sb+sb=?
return new StringBuffer().append(inputNum).reverse().toString();
关于JAVA的题1.关于字符串,下列语句不正确的是________A.String s = new String(”Olympic game”);B.“Welcome to Guangzhou”.indexOf(‘o’); C.String s = “Great Wall”; s.delete(2,5);D.StringBuffer buffer = new StringBuffer(); b
