例子
下面的例子显示math.BigInteger.not()方法的用法
package com.yiibai; import java.math.*; public class BigIntegerDemo { public static void main(String[] args) { // create 4 BigInteger objects BigInteger bi1, bi2, bi3, bi4; // assign values to bi1, bi2 bi1 = new BigInteger("6"); bi2 = new BigInteger("-6"); // perform not operation on bi1 and bi2 bi3 = bi1.not(); bi4 = bi2.not(); String str1 = "Result of not operation on " + bi1 +" gives " +bi3; String str2 = "Result of not operation on " + bi2 +" gives " +bi4; // print bi3, bi4 values System.out.println( str1 ); System.out.println( str2 ); } }
让我们编译和运行上面的程序,这将产生以下结果:
Result of not operation on 6 gives -7 Result of not operation on -6 gives 5
