java - How to compare two strings, and output the first if they're not equal

Question

I have the following problem... I need to compare two string and output the first one if they are not equal. Something like the code below, but printing the first string instead. How can I do it?

String myString1 = new String("abc123");
String myString2 = new String("abc");
if(myString1.equals(myString2))
{
    System.out.println("The two strings are equal");
}
else 
{
    System.out.println("The two strings are not equal");
}

Answer 1

您可以将第一个字符串作为参数传递给System.out.println，如下所示：

if(myString1.equals(myString2)) {
  System.out.println("The two strings are equal");
}
else {
  System.out.println(myString1);
}

Answer 2

您可以使用三元运算符：

String myString1 = new String("abc123");
String myString2 = new String("abc");
System.out.println("The two strings are " +
  (myString1.equals(myString2) ? "" : "not") + " equal";

你也可以使用String.format它。
