Compare two arrays

static boolean equals(boolean[] a, boolean[] a2): Returns true if the two specified arrays of booleans are equal to one another.
static boolean equals(byte[] a, byte[] a2): Returns true if the two specified arrays of bytes are equal to one another.
static boolean equals(char[] a, char[] a2): Returns true if the two specified arrays of chars are equal to one another.
static boolean equals(double[] a, double[] a2): Returns true if the two specified arrays of doubles are equal to one another.
static boolean equals(float[] a, float[] a2): Returns true if the two specified arrays of floats are equal to one another.
static boolean equals(int[] a, int[] a2): Returns true if the two specified arrays of ints are equal to one another.
static boolean equals(long[] a, long[] a2): Returns true if the two specified arrays of longs are equal to one another.
static boolean equals(Object[] a, Object[] a2): Returns true if the two specified arrays of Objects are equal to one another.
static boolean equals(short[] a, short[] a2): Returns true if the two specified arrays of shorts are equal to one another.

Compare Two Java boolean Arrays with Arrays.equals() method.


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {

    boolean[] booleanArray1 = new boolean[] { true, false, true };
    boolean[] booleanArray2 = new boolean[] { true, false, true };
    

    System.out.println(Arrays.equals(booleanArray1, booleanArray2));
  }
}

The output:


true

Compare Two Java byte Arrays for equality using Arrays.equals method


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
    byte[] byteArray1 = new byte[] { 1, 2, 3 };
    byte[] byteArray2 = new byte[] { 3, 2, 1 };

    System.out.println(Arrays.equals(byteArray1, byteArray2));
  }
}

The output:


false

Compare Two Java char Arrays for equality


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
 
    char[] charArray1 = new char[] { 'j', 'a', 'v', 'a' };
    char[] charArray2 = new char[] { 'j', 'a', 'v', 'a' };
    
    System.out.println(Arrays.equals(charArray1, charArray2));
  }
}

The output:


true

Compare Two Java double Arrays for equality


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
 
    double[] doubleArray1 = new double[] { 1.1, 2.2, 3.3 };
    double[] doubleArray2 = new double[] { 1.1, 2.2, 3.3 };
    
    System.out.println(Arrays.equals(doubleArray1, doubleArray2));
  }
}

The output:


true

Compare Two Java float Arrays


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
 
    float[] floatArray1 = new float[] { 1.2f, 2.3f, 3.3f };
    float[] floatArray2 = new float[] { 1.2f, 2.3f, 3.3f };
    System.out.println(Arrays.equals(floatArray1, floatArray2));
  }
}

The output:


true

Compare Two Java int Arrays for equality using Arrays.equals method.


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
 
    int[] intArray1 = new int[] { 1, 2, 3 };
    int[] intArray2 = new int[] { 1, 2, 3 };
    
    System.out.println(Arrays.equals(intArray1, intArray2));
  }
}

The output:


true

Compare Two Java long Arrays for equality using Arrays.equals method.


import java.util.Arrays;

public class Main {
  public static void main(String[] args) {
 
    long[] longArray1 = new long[] { 999999999, 999999999, 999999999 };
    long[] longArray2 = new long[] { 999999999, 999999999, 999999999 };
 
    System.out.println(Arrays.equals(longArray1, longArray2));
  }
}

The output:
