public static void main(String args) { // TODO Auto-generated method stub String str1 = new String("hello"); String str2 = new String("hello"); System.out.println(str1.equals(str2)); } } 要知道究竟,可以看一下String类的equals方法的具体实现,同样在该路径下,String.java为String类的实现。
, indicating a non-empty string. Checking if str1 is null or empty: The code uses an if-else statement to check if str1 is null or empty. It first checks if str1 is equal to null using the == operator. If the condition evaluates to true, it means str1 is null or empty, and...
当我们创建2个String对象是 我们会发现 执行的结果是false true。为什么这次euqals返回的值编程了true?因为此时equals方法不单单是比较物理地址 同时也比较了值, 在String中 equals方法被重写 当物理地址不同时,会进一步比较值,代码如下: if(object instanceof String){} 那么问题来了当我调用 System.out.println(stu...

In the above examples, we have created objects of theObjectclass. Here, theequals()method is used to check if objects are equal to each other. Example 2: Object equals() With String classMain{publicstaticvoidmain(String[] args){// equals() with String objects// create objects of stringS...
To make code more readable, we can use thestream API‘sIntStream.range()in place of the for-loop. Else the remaining logic is the same as the previous example. publicstaticbooleancheckEqualityWithStream(String[]a1,String[]a2){if(a1==a2){returntrue;}if(a1==null||a2==null||a1.length...
