Java ParsePosition equals()用法及代码示例

java.text.ParsePosition类的equals()方法用于检查两个ParsePosition对象是否相同。

用法:

public boolean equals(Object obj)

参数：此方法采用ParsePosition对象，该对象将与当前ParsePosition对象进行比较。

返回值：如果两个ParsePosition对象彼此相等，则它将返回true，否则返回false。

下面是说明equals()方法的示例：

范例1：

// Java program to demonstrate 
// equals() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos_1 
                = new ParsePosition(0); 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos_2 
                = new ParsePosition(0); 
  
            // compare both object 
            // using equals() mehtod 
            boolean i = pos_1.equals(pos_2); 
  
            // display result 
            if (i) 
                System.out.println( 
                    "pos_1 is equals to pos_2"); 
            else
                System.out.println( 
                    "pos_1 is not equal to pos_2"); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println(e); 
        } 
    } 
}

输出：

pos_1 is equals to pos_2

范例2：

// Java program to demonstrate 
// equals() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos_1 
                = new ParsePosition(0); 
  
            // Creating and initializing 
            // new ParsePosition Object 
            ParsePosition pos_2 
                = new ParsePosition(1); 
  
            // compare both object 
            // using equals() mehtod 
            boolean i = pos_1.equals(pos_2); 
  
            // display result 
            if (i) 
                System.out.println( 
                    "pos_1 is equals to pos_2"); 
            else
                System.out.println( 
                    "pos_1 is not equal to pos_2"); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println(e); 
        } 
    } 
}

输出：

pos_1 is not equal to pos_2
