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.");
}
