两个Integer的引用对象传递给一个swap方法的内部进行交换,返回后,两个引用的值是否会发生变化 缓存编程算法 数组元素作为函数的实参时,用法跟普通变量作参数相同,将数组元素的值传递给形参时进行函数体调用,函数调用完返回后,数组元素的值不变。这种传递方式是”值传递“方式,即只能从实参传递给形参,而不能从形参传...
public static int max(int num1, int num2) { int result; if (num1 > num2) result = num1; else result = num2; return result; } 方法调用 Java 支持两种调用方法的方式,根据方法是否返回值来选择。 当程序调用一个方法时,程序的控制权交给了被调用的方法。当被调用方法的返回语句执行或者到达方法...
