Object中这个方法是这样定义的 publicString toString() {returngetClass().getName() + "@" +Integer.toHexString(hashCode()); } 所以打印结果为classname+@hashcode 当重写了toString方法后,根据java的动态绑定原理,调用的为当前对象的toString()方法,所以当你重写了student的toString方法后,打印结果不再是ttt@1234...

在Java中,重写toString()方法的主要目的是为了方便调试和日志记录。通过重写toString()方法,我们可以将对象的属性以更可读的方式打印出来,便于我们观察对象的状态和调试代码。 默认的toString方法 让我们来看一个简单的例子: publicclassPerson{privateStringname;privateintage;publicPerson(Stringname,intage){this.name=na...

下面的程序说明了toString()方法在java中的使用。 例1:将大十进制数转换为字符串的例子,没有科学符号。 // Java program to demonstrate// toString() method of BigDecimalimportjava.math.*;classGFG{publicstaticvoidmain(String[]args){// Creating a BigDecimal objectBigDecimalb;// Object of String to ho...
Every class in Java is a child of theObjectclass either directly or indirectly. And since theObjectclass contains atoString()method, we can calltoString()on any instance and get its string representation. In this tutorial, we’ll look at thedefault behavior oftoString()and learn how to change...
