1、Java上机实验判断点是否在圆上packagejavaapplication1;importjava.util.Scanner;publicclassEX3_1{publicstaticvoidmain(String[]args){Scannerinput=newScanner(System.in);System.out.print("输入横坐标x：");doublex=input.nextDouble();System.out.print("输入横坐标y：");doubley=input.nextDouble();doubledistance=Math.sqrt(x*x+y*y)

2、;if((distance-1.0)<0.001){System.out.println("点("+x+","+y+")Y");}else{System.out.println("点("+x+","+y+")N");}}}
