這是檢查餘額符號的代碼。 但是，當我嘗試裝入測試儀時， 未正確顯示安裝程序。餘額入住Java
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class BalanceCheck {
private static Scanner in;
public static void main(String[] args){
if(args.length > 0){
System.out.println(args[0]);
try {
in = new Scanner(new File(args[0]));
MyStack<Character> stack = new MyStack<>();
String str;
char ch;
while(in.hasNext()){
str = in.next();
for(int i = 0; i < str.length(); ++i){
ch = str.charAt(i);
if(ch == '(' || ch == '[' || ch == '{' ||
(ch == '/' && i < str.length() - 1 && str.charAt(i+1) == '*')){
stack.push(ch);
}
else if(ch == ')'){
if(stack.isEmpty() || stack.pop() != ch){
System.out.println(") is mismatched");
return;
}
}
else if(ch == ']'){
if(stack.isEmpty() || stack.pop() != ch){
System.out.println("] is mismatched");
return;
}
}
else if(ch == '}'){
if(stack.isEmpty() || stack.pop() != ch){
System.out.println("} is mismatched");
return;
}
}
else if(ch == '*' && i < str.length() - 1 && str.charAt(i+1) == '/'){
if(stack.isEmpty() || stack.pop() != '/'){
System.out.println("*/ is mismatched");
return;
}
}
else if(ch == '"'){
if(stack.isEmpty() || stack.top() == '"'){
if(!stack.isEmpty())
stack.pop();
}
else{
stack.push(ch);
}
}
}
}
in.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
else{
System.out.println("Command line argument is not provided..");
}
}
}
舉例來說，如果我編譯這個測試儀，
/*this tests an unbalanced [ operator*/
public class Test1 {
/* this is the main method */
public static void main(String[) args) {
String ghana = "hello";
int test = testing();
}
public int testing() {
/*checking this too */
/* and this */
return 1;
}
}
它應該顯示[不匹配。但是，它顯示/ *不匹配。
請讓我知道解決方案。
我必須爲上面的代碼創建一個測試器文件。
我該如何爲此測試代碼？
感謝，
