a+=b 可以想象成 a=a+b; 变量声明完了之后,可以使用赋值语句(assignment statement)给变量赋一个值,Java中使用等号(=)作为基本的赋值运算符(assignment operator), 格式如下: variable = expression; 变量= 表达式; 变量我们已经知道如何声明,表达式具体如何定义? 表达式的定义: 表达式涉及到值(常量),变量和通过...
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; Try it Yourself » The addition assignment operator (+=) adds a value to a variable:...

Java assignment operator The assignment operator=assigns a value to a variable. Avariableis a placeholder for a value. In mathematics, the = operator has a different meaning. In an equation, the=operator is an equality operator. The left side of the equation is equal to the right one. ...
Java Variables are assigned, or given, values using one of the assignment operators. The variable are always on the left-hand side of the assignment operator and the value to be assigned is always on the right-hand side of the assignment operator. The assignment operator is evaluated from ...

Java ensures that the value of the right-hand operand of the assignment operator is assignment compatible to the data type of the left-hand operand. Otherwise, acompile-time erroroccurs. In case of reference variables, you may be able to compile the source code and get a runtimeClassCastExc...
