Write a Java program to find the square root of a number using the Babylonian method. Sample Solution: Java Code: importjava.util.*;publicclasssolution{publicstaticfloatsquare_Root(floatnum){floata=num;floatb=1;doublee=0.000001;while(a-b>e){a=(a+b)/2;b=num/a;}returna;}publicstaticvo...
除了使用乘法运算符和Math类的pow()方法外,我们还可以编写自定义方法来计算平方。 publicclassSquareCalculator{publicstaticintcalculateSquare(intnumber){returnnumber*number;}publicstaticvoidmain(String[]args){intnumber=5;intsquare=calculateSquare(number);System.out.println("The square of "+number+" is "+...
How to Square a Number in Java? The first and simplest method is to multiply the number by itself, as shown below: int number = 2; int square = number*number; System.out.println(square); Copy Simple and sweet, isn’t it? Just for the sake of fun, let us take the input from...

classSquareextendsShape{ voiddraw(){ System.out.println("Square.draw()"); } } classTriangleextendsShape{ voiddraw(){ System.out.println("Triangle.draw()"); } } 当使用多态方式调用方法时,首先检查父类中是否有该方法,如果没有,则编译错误;如果有,再去调用子类的同名方法。
