static int cCount = 0 ; //字符统计
static int nCount = 0 ; //数字统计
static int sCount = 0 ; //空格统计
static int oCount = 0 ; //其他符号统计

public static void main(String[] args){
String msg = "what'%91 @ name " ;
byte[] chars = msg.getBytes();
if(chars!=null){
for(byte c:chars){
if(c==32){
sCount++;
}else if(c>=65&&c<=122){
cCount++;
}else if(c>=48&&c<=57){
nCount++;
}else{
oCount++;
}
}
}
System.out.println("该字符串"+msg+"中,字符数["+cCount+"]、数字数["+nCount+"]、空格数["+sCount+"]、其他符号数["+oCount+"]");
}
