字符串与数组的转换+字符串截取

//字符串转换为数组

String string = "a,b,c";String [] stringArr= string.split(","); 

//注意分隔符是需要转译滴...如果是"abc"这种字符串,就直接

String string = "abc" ;char [] stringArr = string.toCharArray(); 

//注意返回值是char数组如果要返回byte数组就直接使用getBytes方法

String string = "abc" ;byte [] stringArr = string.getBytes();

java中如何将字符数组转换成字符串

String[] ary = {"abc", "123", "45"}; StringBuffer sb = new StringBuffer(); for(int i = 0; i < ary.length; i++){ sb. append(ary[i]); } String newStr = sb.toString();
