Java 中 Character.equals()方法，示例
原文:https://www . geesforgeks . org/character-equals-method-in-Java-with-examples/
java . lang . character . equals()是 Java 中的一个函数，它将这个对象与指定的对象进行比较。如果参数不为空，则结果为真，并且是一个字符对象，表示与该对象相同的字符值。
语法:
public boolean equals(Object obj)
参数:该函数接受单个参数对象，该参数指定要比较的对象。
返回值:函数返回一个布尔值。如果对象相同，则返回 true，否则返回 false。
下面的程序说明了上述方法:
程序 1:
// Java program to demonstrate the function
// Character.equals() when two objects are same
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
// assign values to c1, c2
Character c1 = new Character('Z');
Character c2 = new Character('Z');
// assign the result of equals method on c1, c2 to res
boolean res = c1.equals(c2);
// print res value
System.out.println(c1 + " and " + c2 + " are equal is " + res);
}
}
输出:
Z and Z are equal is true
程序二:
// Java program to demonstrate function
// when two objects are different
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
// assign values to c1, c2
Character c1 = new Character('a');
Character c2 = new Character('A');
// assign the result of equals
// method on c1, c2 to res
boolean res = c1.equals(c2);
// prints the res value
System.out.println(c1 + " and " + c2 + " are equal is " + res);
}
}
输出:
a and A are equal is false
