If you want to access the methods and constants of the class scope in Spel, you depend on the key operator of T (). For example, to express Java's math class in Spel, you need to use the T () operator in the following way:T{java.lang.math}The result

Ternary operator: (? ：） the ternary operator, a shorthand for conditional judgments, declares a conditional recipient of a type , evaluates to True to assign the preceding value to the received variable name, and evaluates to false. assigns the

Ruby supports a modern language of a rich array of operators. Most operators are actually method calls. For example, A + B is interpreted as a, + (b) The method of the object referenced by the variable is called a parameter with B as its. For each

Front. There are a total of 46 operators in JavaScript, and there are many operators in addition to the arithmetic, relational, bitwise, and logical operators described earlier. This article describes the conditional operator, the comma operator,
