Java 구동 시간 체크

java

long number1startTime = System.currentTimeMillis();	//시간 선언
System.out.println("number1startTime = " + number1startTime);	//1구간

long number2StartTime = System.currentTimeMillis();
        System.out.println("number2StartTime = " + number2StartTime);	//2구간
        

long number3StartTime = System.currentTimeMillis();
        System.out.println("number3StartTime = " + number3StartTime); //3구간
        
        .
        .
        .
        
        System.out.println(" 총 소요시간 = " + (number5StartTime - number1startTime));
            System.out.println("5구간 - 4구간 = " + (number5StartTime - number4StartTime));
            System.out.println("4구간 - 3구간 = " + (number4StartTime - number3StartTime));
            System.out.println("3구간 - 2구간 = " + (number3StartTime - number2StartTime));
            System.out.println("2구간 - 1구간 = " + (number2StartTime - number1startTime));
            
            //구간별로 소요시간 구할수 있음
            
            ```
