是的，Java中的String类重写了equals方法。重写原因：在Java中，每个对象都继承自Object类，而Object类提供的默认equals方法使用“==”运算符比较两个对象的引用。对于String类来说，比较两个字符串的内容是否相同比比较它们是否指向同一个字符串对象更有意义。因此，String类重写了equals方法。重写后的功能：...
String中的equal方法源码如下: 1 /** 2 * Compares this string to the specified object. The result is {@code 3 * true} if and only if the argument is not {@code null} and is a {@code 4 * String} object that represents the same sequence of characters as this 5 * object. 6 * 7...
equals() Return Value returns trueif the strings are equal returns falseif the strings are not equal returns falseif thestrargument isnull Example: Java String equals() classMain{publicstaticvoidmain(String[] args){ String str1 ="Learn Java"; String str2 ="Learn Java"; String str3 ="Lea...

Java中equal和==区别及String创建过程 Java中equal和==区别 1.起因 在一段Java代码中,使用了两种实现方式。 //第一种命令行输入intmain(String[] args){if(args[0] =="-logdb"){ System.out.println("args==-logdb"); }else{ System.out.println("args!=-logdb");...
Java内部将此语句转化为以下几个步骤：(1)先定义一个名为s1的对String类的对象引用变量放到栈中：String s1；(2)在常量池（字符串常量池）中查找有没有存放值为"accp"的地址，如果没有，则开辟一块存放字面值为"accp"，并将这一块内存的指向地址放到栈中s1的变量中。如果已经有了值为"accp"的...
