一.字符串轉換為數(shù)組
1.轉換成String類型的數(shù)組
String string = "abc,def,ghi";
String[] stringArray = string.split("\\,");
// java中通常用split()分割字符串，返回的是一個數(shù)組
for(String a : stringArray){
System.out.println(a);
}
2.轉換成char類型的數(shù)組
String string = "abc,def,ghi";
char[] stringArray = string.toCharArray();
for(char a : stringArray){
System.out.println(a);
}
3.轉換成byte類型的數(shù)組
String string = "abc,def,ghi";
byte[] stringArray = string.getBytes();
for(byte a : stringArray){
System.out.println(a);
}
二.數(shù)組轉換為字符串
1.char類型的數(shù)組轉換成字符串
char[] array = {'1','2','3','4'};
String a = String.copyValueOf(array);
System.out.println(a);
2.String類型的數(shù)組轉換成字符串
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);
