Write a Java program starting with an integer n, divide it by 2 if it is even, or multiply it by 3 and add 1 if it is odd. Repeat the process until n = 1. Sample Solution: Java Code: importjava.util.Scanner;pub
在Main类的main方法中,我们首先创建了一个Divisor对象,然后调用divideByTwo方法将10除以2,并将结果打印出来。 流程图 下面是一个描述Java除以2的流程图示例: 开始输入数值除以2输出结果结束 在上面的流程图中,我们首先从开始节点(A)开始,然后输入一个数值(B),将该数值除以2(C),然后输出结果(D),最后到达结束节...
divideAndRemainder(BigInteger val) Returns an array of two BigIntegers containing (this / val) followed by (this % val). double doubleValue() Converts this BigInteger to a double. boolean equals(Object x) Compares this BigInteger with the specified Object for equality. BigInteger flipBit(int n...
在catch块中,我们使用printStackTrace()方法打印堆栈信息。 运行上述代码,将输出以下堆栈信息: java.lang.ArithmeticException: / by zero at StackTraceExample.divideByZero(StackTraceExample.java:15) at StackTraceExample.main(StackTraceExample.java:8) 1. 2. 3. 上述堆栈信息告诉我们,异常发生在StackTraceExample....

A processor's floating-point unit (FPU) usually has a control word which affects its behavior on certain floating-point events, such as overflow (generating a result too large to represent as a finite value), underflow (generating an especially small result), and divide by zero (e.g. 1.0...

inti = divide(); //finally里面的代码无论何时一定会执行, //主要用于释放资源 System.out.println(i); } publicstaticint divide() { inti = 0; inta = 9; intb = 0; try { i = 2; a = a/b; returni; }catch(Exception e) {
例4-36中,divide()方法通过逻辑判断对除法运算的除数是否为0进行了判断,如果除数为0就使用throw关键字抛出自定义的DivideByMinusException异常对象,然后通过throws关键字抛出异常,并在最后通过try…catch语句捕获异常。从图4-40可以看出,程序执行后判断出除数为0,抛出了指定的异常信息。
