字符串和数组之间的转换

字符串-->数组

① 转换成String类型的数组

String string = "abc,def,ghi";

String[] stringArray = string.split("\\,");

// java中通常用split()分割字符串，返回的是一个数组

  for(String a : stringArray){

    System.out.println(a);

}

② 转换成char类型的数组

String string = "abc,def,ghi";

char[] stringArray = string.toCharArray();

for(char a : stringArray){

System.out.println(a);

}

③ 转换成byte类型的数组

String string = "abc,def,ghi";

byte[] stringArray = string.getBytes();

for(byte a : stringArray){

System.out.println(a);

}

数组-->字符串

① char类型的数组转换成字符串

char[] array = {'1','2','3','4'};

String a = String.copyValueOf(array);

System.out.println(a);

② String类型的数组转换成字符串

String[] strArray = {"1er","2df","3sw","4ui"};

StringBuffer strBuffer = new StringBuffer();

for(int i=0;i<strArray.length;i++){

  strBuffer.append(strArray[i]);

}

String b = strBuffer.toString();

System.out.println(b);
