两个字符串数组如何比较是否相等？

Question

例tmplist1=Id,ProjectId,VersionId,ItemNos,TagNumber,Description,Model,Spec,Quantity,OrificeDia
tmplist2=ItemNos,TagNumber,Model,Spec,OrificeDia,InSize,InRating,Option1,OutSize,OutRating,Option2,Pressure_OperPress,Pressure_SetPress
如何比较他们俩的大小

Answer 1

比较是否相等用equals
比较大小直接用><号

Answer 2

Java中数组之间的比较
    // null 元素是相等的.
    boolean[] bArr1 = null;
    boolean[] bArr2 = null;
    boolean b = Arrays.equals(bArr1, bArr2);                   // true
    
    // 比较两个boolean数组.
    bArr1 = new boolean[]{true, false};
    bArr2 = new boolean[]{true, false};
    b = Arrays.equals(bArr1, null);                            // false
    b = Arrays.equals(bArr1, bArr2);                           // true
    
    // 对于原生类型的数组可以用equals().
    b = Arrays.equals(new byte[]{0}, new byte[]{0});           // true
    b = Arrays.equals(new char[]{'a'}, new char[]{'a'});       // true
    b = Arrays.equals(new short[]{0}, new short[]{0});         // true
    b = Arrays.equals(new int[]{0}, new int[]{0});             // true
    b = Arrays.equals(new long[]{0L}, new long[]{0L});         // true
    b = Arrays.equals(new float[]{0F}, new float[]{0F});       // true
    b = Arrays.equals(new double[]{0D}, new double[]{0D});     // true
    
    // 如果比较的是Object型的数组，null元素是相等的.
    // 如果于元素不是null, Java虚拟机会自动调用Object.equals().
    b = Arrays.equals(new String[]{"a"}, new String[]{"a"});   // true
    b = Arrays.equals(new String[]{null}, new String[]{null}); // true
    b = Arrays.equals(new String[]{"a"}, new String[]{null});  // false
