ch1_1.java

Java环境下实现的数值分析程序

class ch1_1{
	public static void main(String[]args){
		int x,y;
		double sub1=0,sub2=0;
		for(x=1;x<=10000;x++)
			sub1=sub1+Math.pow(x,-2);
		for(y=10000;y>=1;y--)
			sub2=sub2+Math.pow(y,-2);
		System.out.println("sub1="+sub1);
		System.out.println("sub2="+sub2);
	}
}
