testdouble.java

使用了java 的awt包实现的java带有界面的计算器功能

package test;

public class TestDouble {
	public static void main(String[] args) {
		double a,b;
		int e,f;
		
		a=5.6;
		b=3.0;
		e=3;
		
		float c=5.6f;
		float d=3;
		
		System.out.println((a+b));
		System.out.println((a-b));
		System.out.println((a/b));
		System.out.println((a*b));
		System.out.println();
		System.out.println((a+e));
		System.out.println((a-e));
		System.out.println((a*e));
		System.out.println((a/e));
		System.out.println();
		System.out.println((c));
		System.out.println((d));
		System.out.println((c-d));
		System.out.println((a/e));
		
	}
