Java代码中如何判断两个Long类型是否相等呢?

判断long类型是否相等的方法

使用eques()方法或使用longValue()
       即可对两个long类型进行相应的判断
   如下例所示

public class LongTypeEquals {
    public static void main(String[] args) {
        Long oneNum=100L;
        Long twoNum=100L;
        Long oneCommNum127=127L;
        Long twoCommNum127=127L;
 
        Long oneCommNum128=128L;
        Long twoCommNum128=128L;
        Long oneBigNum=10000L;
        Long twoBigNum=10000L;
        //大于-128 小于127的数
        if(oneNum==twoNum){
            System.out.println("oneNum == twoNum");
        }else{
            System.out.println("oneNum != twoNum");
        }
        // 如果大于127的情况
        if(oneCommNum127==twoCommNum127){
            System.out.println("oneCommNum127 == twoCommNum127");
        }else{
            System.out.println("oneCommNum127 != twoCommNum127");
        }
 
        // 如果大于127的情况
        if(oneCommNum128==twoCommNum128){
            System.out.println("oneCommNum128 == twoCommNum128");
        }else{
            System.out.println("oneCommNum128 != twoCommNum128");
        }
 
        //equals 方式比较
        if(oneBigNum.equals(twoBigNum)){
            System.out.println("oneBigNum == twoBigNum");
        }else{
            System.out.println("oneBigNum != twoBigNum");
        }
 
        // longValue 比较
        if(oneBigNum.longValue()==twoBigNum.longValue()){
            System.out.println("oneBigNum == twoBigNum");
        }else{
            System.out.println("oneBigNum != twoBigNum");
        }
 
    }
}
