String和Char的相互转化//JAVA

Char——>String

String s = String.valueOf('c'); //单个字符
String s = String.valueOf(new char[]{'c'}); //转换数组
String s = Character.toString('c');//实际上直接返回String.valueOf(char)
String s = new Character('c').toString();
String s = new String(new char[]{'c'});
String s = "" + 'c';

String——>Char

String.charAt(index)//return char

String.toCharArray()//return char[]
