在下面的代码中，下面的块if(timesout[entry] == "exit")永远不会执行。我已经验证timesout[entry]当前循环在调试模式下设置为“退出”，以及在评估 if 语句之前打印出变量，但无论如何，当我exit在提示符下输入时，该块永远不会执行，并且我我很难过为什么。
import java.util.Scanner;
public class timetracker {
public static void main(String args[]) {
boolean exit = false;
String[] reasons = new String[30];
String[] timesout = new String[30];
String[] timesin = new String[30];
int entry = 0;
Scanner keyinput = new Scanner(System.in);
recordloop:
while(exit == false) {
//record info
System.out.println("Enter time out:");
timesout[entry] = keyinput.nextLine();
if(timesout[entry] == "exit") {
exit = true;
break recordloop;
}
System.out.println("Enter reason:");
reasons[entry] = keyinput.nextLine();
System.out.println("Enter time in:");
timesin[entry] = keyinput.nextLine();
entry = entry + 1;
}
System.out.println("Times away from phone:\n ----- \n");
int count = entry;
entry = entry + 1;
while(count < entry) {
System.out.println(reasons[count] + ": " + timesout[count] + " - " + timesin[count] + "\n");
count = count + 1;
}
}
}
