接下来,我们将创建一个方法,该方法将接受一个FuncInterface类型的参数。 publicclassFunctionAsParameter{publicstaticvoidexecuteFunction(FuncInterfacefunc){func.execute();}} 1. 2. 3. 4. 5. 在上面的代码中,我们创建了一个名为executeFunction()的静态方法,它接受一个FuncInterface类型的参数。该方法中我们调用...
Functional Interface: This is a functionalinterfaceand can therefore be used as the assignment targetfora lambda expression or method reference. @FunctionalInterface publicinterfaceFunction<T,R> Represents a function that accepts one argument and produces a result. This is a functionalinterfacewhose func...

Nodes分为两类:ExprNode和ParameterNode。通过成员函数asExpr和asParameter可以将Node映射为expressions/parameters。 classNode{/** Gets the expression corresponding to this node, if any. */ExprasExpr(){...}/** Gets the parameter corresponding to this node, if any. */ParameterasParameter(){...}....
当我们调用arrow functions时,它们没有自己的隐式的this参数;它们只记得 在创建它们时 this参数的值。...所有的`function`都有`bind method`这个方法,该方法创建并返回一个`新的function`,这个`新的function`被绑定到传入的对象上。...不管`新的functi...

We can replace a lambda expression with a method reference if it directly routes the parameter as an argument to a method on another instance; for example, println() on System.out. The preceding sample code is equivalent to this: str.chars().forEach(ch-> System.out.println(ch)); ...
@Target({TYPE, FIELD, METHOD, PARAMETER, CONSTRUCTOR, LOCAL_VARIABLE}) @Retention(RetentionPolicy.SOURCE) public @interface SuppressWarnings { String[] value(); } 我们可以看到,它只定义了一个注解方法value(),它的返回值类型为String[],没有指定默认返回值。我们使用@SuppressWarnings这个注解所用的语法如...
