Java ZoneOffsetTransition isOverlap()用法及代码示例

java.time.zone.ZoneOffsetTransition类的isOverlap()方法用于检查过渡之间是否存在重叠。

用法:

public boolean isOverlap()

参数：此方法不接受任何参数。

返回值：如果过渡之间没有重叠，则此方法返回true。

下面是说明isOverlap()方法的示例：

范例1：

// Java program to demonstrate 
// isOverlap() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // the object of LocalDateTime 
        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 
                03, 24, 59, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofHoursMinutes(0, 8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(9); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // comparing both object using 
        // equals() method 
        boolean status = zonetrans1.isOverlap(); 
  
        // display the result 
        if (status) 
            System.out.println( 
                "there is an overlapping"); 
        else
            System.out.println( 
                "no overlapping found"); 
    } 
}

输出：

there is an overlapping

范例2：

// Java program to demonstrate 
// isOverlap() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // the object of LocalDateTime 
        LocalDateTime loc 
            = LocalDateTime.of( 
                1999, 04, 25, 
                03, 24, 59, 0); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off1 
            = ZoneOffset.ofTotalSeconds(8); 
  
        // creating and initializing 
        // the object of ZoneOffset 
        ZoneOffset off2 
            = ZoneOffset.ofTotalSeconds(12); 
  
        // creating and initializing 
        // ZoneOffsetTransition Object 
        ZoneOffsetTransition zonetrans1 
            = ZoneOffsetTransition.of( 
                loc, off1, off2); 
  
        // comparing both object using 
        // equals() method 
        boolean status = zonetrans1.isOverlap(); 
  
        // display the result 
        if (status) 
            System.out.println( 
                "there is an overlapping"); 
        else
            System.out.println( 
                "no overlapping found"); 
    } 
}

输出：

no overlapping found
