Yes, the if the two string objects point to the same memory location. But "==" is not the best way to compare two string objects. Two strings can be compared using obj1.equals(obj2). This compares for the textual equal-ness of the two string objects.

What does equals equals mean in java?
operator to compare two objects. The simple "=" sign is used for assignment - assigning a value to a variable. Here are examples of the two: x = 15; // Assign the value 15 to the variable if (x == 10) ... // Compare variable "x" with some value
How do you find out not equals string in java?
Remember that strings are objects. You can use the String.equals method to determine equality, and use the ! (not) operator to test for inequality. public static boolean notEquals(String str1, String str2) { return !str1.equals(str2); }
What is the use of 'compareTo' in java?
To compare the contents of two objects. The equality, "=", will simply tell you whether two objects are in the same memory location; it doesn't tell you whether their contents are actually the same. To compare the contents, there is an equals() method which tells you whether the contents are actually equal; there is also a compareTo() which can also tell you which of two objects is "greater". Since objects can be quite complex, the programmer may have to overwrite the (often useless) default behavior of these methods.
Is x plus equals y is post increment or pre increment?
The '+=' operator behaves like a pre increment operator.

What is difference between equals and equals equals operators?
The equals operator is used for assigning a value to a variable. ex String name = "efu"; the equals equals operator is used for comparaing if the given value is equal to another value which is assigned for a variable. ex int i = 0; int j = 5; if( i == 0){ System.out.println(j+"can't be divided by"+i); }else{ System.out.println("answer is " +j/i); }
Is a syntax B1-B2B3 is an example of formula in excel?
No. There is no equals sign at the start and the cell reference B2B3 is not valid or has an operator missing.
