Java程序比较两个Java浮点数组
要比较Java浮点数组，请使用Arrays.equals()方法。返回值是一个布尔值。假设我们有以下float数组-
float[] floatVal1 = new float[] { 3.2f, 5.5f, 5.3f };
float[] floatVal2 = new float[] { 8.3f, 8.8f, 9.2f };
float[] floatVal3 = new float[] { 6.2f, 6.9f, 9.9f };
float[] floatVal4 = new float[] { 3.2f, 5.5f, 5.3f };为了比较它们，将使用Arrays.equals()方法-
Arrays.equals(floatVal1, floatVal2); Arrays.equals(floatVal2, floatVal3); Arrays.equals(floatVal3, floatVal4);
以下是完整的示例，其中我们比较了所有数组-
示例
import java.util.Arrays;
public class Demo {
public static void main(String args[]) {
float[] floatVal1 = new float[] { 3.2f, 5.5f, 5.3f };
float[] floatVal2 = new float[] { 8.3f, 8.8f, 9.2f };
float[] floatVal3 = new float[] { 6.2f, 6.9f, 9.9f };
float[] floatVal4 = new float[] { 3.2f, 5.5f, 5.3f };
System.out.println(Arrays.equals(floatVal1, floatVal2));
System.out.println(Arrays.equals(floatVal2, floatVal3));
System.out.println(Arrays.equals(floatVal3, floatVal4));
System.out.println(Arrays.equals(floatVal1, floatVal3));
System.out.println(Arrays.equals(floatVal1, floatVal4));
}
}输出结果
false false false false true
