如何在 Java 中初始化和比较字符串?
你可以使用 compareTo() 方法或 equals() 方法或 == 运算符比较字符串。以下示例演示如何在 Java 中初始化并比较字符串。
示例
实时演示public class StringDemo { public static void main(String[] args) { String str1 = "tutorials"; String str2 = "point"; // comparing str1 and str2 int retval = str1.compareTo(str2); // prints the return value of the comparison if (retval < 0) { System.out.println("str1 is greater than str2"); } else if (retval == 0) { System.out.println("str1 is equal to str2"); } else { System.out.println("str1 is less than str2"); } } }
输出
str1 is less than str2
