在Java中,可以使用equals()方法来比较两个字符串是否相等。示例如下:
String str1 = "Hello"; String str2 = "World"; if(str1.equals(str2)) { System.out.println("The two strings are equal."); } else { System.out.println("The two strings are not equal."); }
另外,还可以使用equalsIgnoreCase()方法来忽略大小写比较两个字符串是否相等。示例如下:
String str1 = "hello"; String str2 = "HELLO"; if(str1.equalsIgnoreCase(str2)) { System.out.println("The two strings are equal ignoring case."); } else { System.out.println("The two strings are not equal ignoring case."); }
