Variables and array elements are all references to objects. They are not the actual objects. To illustrate, I’ll “name” actual objects using a number scheme, e.g. #1 is the first object. Your code runs as follows: Class is initialized by the JVM, and root1, root2, and root3 are all null. Node root[]={root1,root2,root3} is executed and … Read more
I think this is what you meant, the following code loops through all rows with data, and for each row checks if the word “man” is inside that strings (using the Instr function).

An enum is basically a special type that lets you define named values. You’re creating a named type just as you would if you were defining a class. What your code is actually doing is first defining your enumerated type called States with all the possible named values, then declaring a variable “myState” using the … Read more
Try This void test() { if(number<1) { number = 1; } Log.e(“number value : “,String.valueOf(number)); btn1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { if(number == 1) { number=2; Log.e(“Button 1 number value : “,String.valueOf(number)); } } }); btn2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { if(number == 2) { number=1; Log.e(“Button 2 number … Read more
You can foreach to loop through all item and call in the array like: foreach($yourArray as $item) { echo $item->label; echo $item->file; } Or you can be using json_decode to cast your object to the array. $result = json_decode($data, true); 2 solved How to echo values from this array? [duplicate]
You can use StringBuffer or StringBuilder for this task, StringBuilder would be my choice since its more efficient. its not thread safe so multiple threads can call its methods simultaneously. String reversedString = new StringBuilder(originalString).reverse().toString() If you prefer not to use API support you can do something like this static String reverse(String stringIn) { char[] … Read more
It’s simply how Java is specified. From JLS Sec 15.26, the grammar of the assignment is given by: Assignment: LeftHandSide AssignmentOperator Expression LeftHandSide: ExpressionName FieldAccess ArrayAccess So the LHS has to be either a variable, a field or an array element. Anything else is invalid syntax. The reason why you can’t reassign a method’s return … Read more

If you wanted to be real fancy, you could write an anonymous function to do this since you can then use inputname to infer the name of the input variable. func = @(var)fprintf(‘\n%s size: %s\n’, inputname(1), num2str(size(var))) x = rand(10, 4); func(x) % x size: 10 4 You can also just use fprintf fprintf(‘\n%s size: … Read more

There is no equality operator defined for the sf::RectangleShape class. You will need to create one, and decide on exactly what properties determine equality. Perhaps size and position are what you care about. So you could define the following function: bool operator==( const sf::RectangleShape & a, const sf::RectangleShape & b ) { return a.getSize() == … Read more
