Note: The compound assignment operator in Java performs implicit type casting. Let's consider a scenario where x is an int variable with a value of 5. int x = 5; If you want to add the double value 4.5 to the integer variable x and print its value, there are two methods to achieve this: Method 1: x = x + 4.5. Method 2: x += 4.5.
You can also combine the arithmetic operators with the simple assignment operator to create compound assignments. For example, x+=1; and x=x+1; both increment the value of x by 1. The + operator can also be used for concatenating (joining) two strings together, as shown in the following ConcatDemo program:
Java Assignment Operators. Assignment operators are used to assign values to variables. In the example below, we use the assignment operator (=) to assign the value 10 to a variable called x: Example int x = 10;
To assign a value to a variable, use the basic assignment operator (=). It is the most fundamental assignment operator in Java. It assigns the value on the right side of the operator to the variable on the left side. Example: int x = 10; int x = 10; In the above example, the variable x is assigned the value 10.
Java assignment operators are classified into two types: simple and compound. The Simple assignment operator is the equals ( =) sign, which is the most straightforward of the bunch. It simply assigns the value or variable on the right to the variable on the left. Compound operators are comprised of both an arithmetic, bitwise, or shift operator ...
Learning the operators of the Java programming language is a good place to start. Operators are special symbols that perform specific operations on one, two, or three operands, and then return a result. As we explore the operators of the Java programming language, it may be helpful for you to know ahead of time which operators have the highest ...
Java Assignment Operators. The Java Assignment Operators are used when you want to assign a value to the expression. The assignment operator denoted by the single equal sign =. In a Java assignment statement, any expression can be on the right side and the left side must be a variable name. For example, this does not mean that "a" is equal to ...
Example. =. Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign value of A + B into C. +=. Add AND assignment operator. It adds right operand to the left operand and assign the result to left operand. C += A is equivalent to C = C + A.
Next, let's see which assignment operators we can use in Java. 9.1. The Simple Assignment Operator. The simple assignment operator (=) is a straightforward but important operator in Java. Actually, we've used it many times in previous examples. It assigns the value on its right to the operand on its left:
Java is the foundation for virtually every type of networked application and is the global standard for developing and delivering embedded and mobile applications, games, Web-based content, and enterprise software. With more than 9 million developers worldwide, Java enables you to efficiently develop, deploy and use exciting applications and ...
The following assignment operators are supported in Java. The associativity of assignment operator is "right to left", which means the when compiler encounters assignment operator, it starts to evaluate the expression from right to left. For example: int num = 10; The compiler assigns the value 10 to the variable num. 1. = Operator example
Compound Assignment Operators. Sometime we need to modify the same variable value and reassigned it to a same reference variable. Java allows you to combine assignment and addition operators using a shorthand operator. For example, the preceding statement can be written as: i +=8; //This is same as i = i+8; The += is called the addition ...
Java Assignment Operators. Assignment operators are used in Java to assign values to variables. For example, int age; age = 5; Here, = is the assignment operator. It assigns the value on its right to the variable on its left. That is, 5 is assigned to the variable age.
In this lesson, you will learn about assignment statements and expressions that contain math operators and variables. 1.4.1. Assignment Statements ¶. Remember that a variable holds a value that can change or vary. Assignment statements initialize or change the value stored in a variable using the assignment operator =.
a |= b; is the same as. a = (a | b); It calculates the bitwise OR of the two operands, and assigns the result to the left operand. To explain your example code: for (String search : textSearch.getValue()) matches |= field.contains(search); I presume matches is a boolean; this means that the bitwise operators behave the same as logical operators.

I believe that your problem is due to the fact that you are defining the variable v inside the test. As explained by @rmalchow, it will work you change it into
JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented ...
The |= is a compound assignment operator ( JLS 15.26.2) for the boolean logical operator | ( JLS 15.22.2 ); not to be confused with the conditional-or || ( JLS 15.24 ). There are also &= and ^= corresponding to the compound assignment version of the boolean logical & and ^ respectively. In other words, for boolean b1, b2, these two are ...
Currently, Android and Java ME are used for creating mobile applications. Java Platforms / Editions.
