자바 패턴 프로그램 코딩 기술, 논리 및 루핑 개념을 향상시킵니다. 주로 다음과 같이 질문합니다. 자바 인터뷰 프로그래머의 논리와 사고를 확인합니다. 우리는 자바 패턴 프로그램 다른 디자인으로. 패턴 프로그램을 배우려면 다음과 같은 Java 루프에 대한 깊은 지식이 있어야 합니다. ~을 위한 고리 하는 동안 고리. 이 섹션에서는 다음 내용을 학습합니다. Java에서 패턴을 인쇄하는 방법 .
우리는 자바 패턴 프로그램 세 가지 범주로:
패턴 프로그램으로 이동하기 전에 접근 방식을 살펴 보겠습니다.
패턴 프로그램의 로직을 설계할 때마다 먼저 다음 이미지에 표시된 대로 블록에 해당 패턴을 그립니다. 그림은 패턴의 명확한 모습을 보여줍니다.
버킷 정렬
각 패턴 프로그램에는 2개 이상의 루프가 있습니다. 루프 수는 패턴이나 로직의 복잡성에 따라 달라집니다. 첫 번째 for 루프는 행에 대해 작동하고 두 번째 루프는 열에 대해 작동합니다. 패턴 프로그램에서는 자바 for 루프 널리 사용됩니다.
위의 패턴에서, 열 로 표시된다 나 그리고 열 로 표시된다 제이 . 첫 번째 행에는 별표만 인쇄되는 것을 볼 수 있습니다. 두 번째 행에는 별 두 개가 인쇄됩니다. 그만큼 색깔의 블록은 인쇄 공백 .
위에 제시된 패턴에 대한 논리를 만들어 보겠습니다. 다음 코드 조각에서는 행과 열 값을 0부터 시작합니다. 1부터 시작할 수도 있으며 원하는 대로 선택할 수 있습니다.
